Al-Qaida in the Arabian Peninsula has claimed responsibility for the attempted attack on a US airliner on Christmas day, saying it was retaliation for a US operation against the group in Yemen.
In a statement posted on the Internet on Monday, the group said 23-year-old Nigerian Umar Farouk Abdulmutallab coordinated with members of the group.
Yemeni forces, helped by US intelligence, carried out two airstrikes against al-Qaida operatives in the country this month. The second one was a day before the attempted bombing of the plane.
The group said the would-be bomber used explosives manufactured by al-Qaida members. Al-Qaida in the Arabian Peninsula is an alliance of militants based in Saudi Arabia and Yemen.
