US militant vows to avenge bin Laden's death

An American fighting for an al-Qaida linked militant group in wartorn Somalia is threatening to avenge the death of Osama bin Laden.

Omar Hammami, known as Abu Mansur al-Amriki, or "the American," said Wednesday that bin Laden's death does not mean the end of attacks against U.S. interests.

Hammami is among hundreds of foreign fighters in the ranks of the al-Shabab, Somalia's most dangerous militant group, that is trying to topple the country's weak U.N.-backed government.

Al-Shabab carried out its first international attack last July in Uganda,killing 76 people watching the World Cup final in two bomb explosions.

Hammami grew up in the middle-class town of Daphne, Alabama, before joining the militants in 2007.
