A Yemeni official has blamed al-Qaida for this month's attack targeting the U.S. Embassy in the capital of Sanaa.

The anonymous official says the main suspect in the attack is al-Qaida militant Hamza al-Dayan.  Al-Dayan and several other men are accused with launching two mortars at a girls' school near the embassy. The attack killed at least one Yemini security guard, and wounded several other people, including children.

Yemen joined the U.S.-led war against terrorism after the September 11, 2001 attacks.  The country has witnessed a number of militant attacks targeting foreign tourists, oil installations and U.S. and French ships.

A suicide attack on a U.S. naval destroyer, the USS Cole, while it was anchored off the southern Yemeni port of Aden in October 2000 left 17 sailors dead.
