Second Militant Group Claims Responsibility for London Bombing

A second group that says it has links to the al-Qaida terrorist network has claimed responsibility for Thursday's attacks in London.

A group calling itself the "Abu Hafs al-Masri Brigades" posted a statement on an Arabic language Islamist website Saturday, congratulating itself for the bombings on three subway trains and one bus in the central part of the British capital.

The same group also claimed responsibility for the March, 2004 Madrid train bombings that killed nearly 200 people.

Just hours after Thursday's bombings, a group calling itself "The Secret Organization of al-Qaida in Europe" issued a statement on another Arabic language Islamist website claiming responsibility for the attacks.

Neither claim has been verified.
