The suspected al-Qaida figure nabbed by US special forces in a dramatic operation in the Libyan capital had been living freely in his homeland after his return there three years ago, his family said. Libya's government asked for an explanation Sunday from the United States after the Americans seized Abu Anas al-Libi from a Tripoli street outside his home and whisked him out of the country.

The raid that captured al-Libi was one of two dramatic American raids on the ground in African countries targeting suspected terrorists on Saturday. In Somalia, a Navy SEAL team swam ashore early the same day and engaged in a fierce firefight, thought it did not capture its target, a militant suspected in the recent Kenyan mall siege.

The operations — one in North Africa, the other in the Horn of Africa — were a startling move to pursue terror suspects directly in two countries mired in chaos where the United States has suffered bloody humiliations in the past.

"We hope that this makes clear that the United States of America will never stop in the effort to hold those accountable who conduct acts of terror," US Secretary of State John Kerry said Sunday while in Indonesia for an economic summit. "Members of al-Qaida and other terrorist organizations literally can run but they can't hide."

The Pentagon identified the figure seized in the Libyan capital Saturday as Nazih Abdul-Hamed al-Ruqai, known by his alias Abu Anas al-Libi, who is accused by the US of involvement in the 1998 bombings of two American embassies in Africa. He has been on the FBI's most wanted terrorists list since it was introduced shortly after the Sept. 11, 2001 attacks. There was a $5 million bounty on his head.

The US Defense Department's chief spokesman, George Little, said the suspect is "lawfully detained under the law of war in a secure location outside of Libya." Little's statement did not elaborate.

Al-Libi was indicted by a federal court in New York for his alleged role in the bombings of the US Embassies in Dar es Salaam, Tanzania, and Nairobi, Kenya, on August 7, 1998, that killed more than 220 people.

But it was not immediately clear if he had been involved with al-Qaida since or had been connected to militant activities in Libya, where al-Qaida has a growing presence since the 2011 ouster of Moammar Gadhafi.

His family denied he was ever a member of al-Qaida and said he was not involved in militant activity since his return.

Al-Libi's son Abdullah al-Ruqai told The Associated press his father was a member of the Armed Islamic Fighting Group, an Islamic militant group that battled Gadhafi's regime, many of whose members were forced to flee the country in the 1990s. Some members later linked with al-Qaida, but others did not. Abdullah said his father and the family were in Afghanistan for about a year in and half in the early 2000s.

Al-Libi was then imprisoned in Iran for seven years, Abdullah said. He did not elaborate, but Iran jailed a number of al-Qaida-linked figures who fled Afghanistan after the 2001 US-led invasion of that country.

The family returned to Tripoli in 2010 under a rehabilitation program run by Gadhafi's son. Since then, al-Libi was not involved with any groups. "He would go from the house to the mosque, and from the mosque to the house," the son said. He said his father had hired a lawyer and was trying to clear his name in connection to the 1998 African embassy attacks.

A senior US military official said the Tripoli raid was carried out by the US Army's Delta Force, which has responsibility for counterterrorism operations in North Africa. The official was not authorized to speak publicly about the operation and discussed it on condition of anonymity.

Family members said gunmen in a three-car convoy seized al-Libi outside his home in the Libyan capital.

His brother, Nabih, said the 49-year-old was parking outside his house early Saturday after dawn prayers, when three vehicles surrounded his vehicle. The gunmen smashed his car's window and seized his gun before grabbing al-Libi and fleeing. The brother said al-Libi's wife saw the kidnapping from her window and described the abductors as foreign-looking armed "commandos."

Libya asked the United States on Sunday for "clarifications" regarding the raid and said any Libyan should face trial in his own country.

The raid puts the fragile Libyan government in a delicate position — the country's post-Gadhafi leadership faces criticism from some Libyans that it is too close to the United States, and it cannot be seen to be allowing US forces to act freely on Libyan territory. The central government has had only limited authority around the country, where militiamen — many of the Islamic militants themselves — hold considerable power and have unleashed their anger on the government in the past.

The country's turmoil has allowed al-Qaida and other militant groups to increase their activity here.On Sept. 11, 2011, militants attacked the US consulate in Benghazi, Libya's second largest city, killing the American ambassador and three other Americans, an attack that demonstration the power of militias and the weakness of the government.

Al-Libi was believed to be a computer specialist with al-Qaida. He studied electronic and nuclear engineering, graduating from Tripoli University, and was an anti-Gadhafi activist.

He is believed to have spent time in Sudan, where bin Laden was based in the early 1990s. After bin Laden was forced to leave Sudan, al-Libi turned up in Britain in 1995 where he was granted political asylum under unclear circumstances and lived in Manchester. He was arrested by Scotland Yard in 1999, but released because of lack of evidence and later fled Britain.

In the earlier raid Saturday, the Navy SEAL team reached land near a town in southern Somalia before militants of the al-Qaida-linked terrorist group al-Shabab rose for dawn prayers, US and Somali officials told The Associated Press. American officials said there were no US casualties in either the Somali or Libyan operation.

The assault on a house in Barawe targeted a specific al-Qaida suspect related to the Nairobi mall attack, but the operation did not get its target, one current and one former US military official told the AP. It was carried out by members of SEAL Team Six, the same unit that killed in Laden in his Pakistan hideout in 2011, another senior US military official said.

Both spoke on condition of anonymity because they were not authorized to discuss the raid publicly.

The team ran into fiercer resistance than expected, and after a 15 minutes to 20 minute firefight, the unit's leader decided to abort the mission and the Americans swam away, the official said. SEAL Team Six has responsibility for counterterrorism activities in the Horn of Africa.

A US official said US forces disengaged after inflicting some casualties on the fighters, said the official, who was not authorized to speak by name and insisted on anonymity.

A resident of Barawe, which is about 150 miles south of Mogadishu, said by telephone that heavy gunfire woke up residents before dawn prayers.

The US forces attacked a two-story beachside house where foreign fighters lived, said an al-Shabab fighter who gave his name as Abu Mohamed and who said he had visited the scene.

An al-Shabab official, Sheikh Abdiaziz Abu Musab, said in an audio message that the raid failed to achieve its goals.

Little confirmed that US military personnel were involved in a counterterrorism operation against a known al-Shabab terrorist in Somalia, but did not provide details.

The leader of al-Shabab, Mukhtar Abu Zubeyr, also known as Ahmed Godane, claimed responsibility for the mall attack, a four-day terrorist siege that began Sept. 21 and killed at least 67 people. A Somali intelligence official said the al-Shabab leader was the US target.

Kerry said the United States would "continue to try to bring people to justice in an appropriate way with hopes that ultimately these kinds of activities against everybody in the world will stop."

Al-Shabab has a formal alliance with al-Qaida, and hundreds of men from the US, Britain and Middle Eastern countries fight alongside Somali members of al-Shabab.

Al-Shabab and al-Qaida have flourished in Somalia for years.

The raid in Somalia came 20 years after the "Black Hawk Down" battle in Mogadishu, when a mission to capture Somali warlords in the capital went awry after militiamen shot down two US helicopters. Eighteen US soldiers died in the battle, which marked the beginning of the end of that US military mission to try to bring stability to the nation.

Since then, US military intervention has been limited to missile attacks and lightning operations by special forces.

In September 2009 a daylight commando raid in Barawe killed six people, including Saleh Ali Saleh Nabhan, one of the most-wanted al-Qaida operatives in the region and an alleged plotter in the embassy bombings.

Al-Shabab later posted pictures on the Internet of what it said was US military gear left behind in the raid. Pictures showed items including bullets, an ammunition magazine, a military GPS device and a smoke and flash-bang grenade used to clear rooms.
