Forty-one people were killed and dozens more wounded Friday in a suicide bombing at a mosque in the northern Afghan city of Maymana, officials told Efe.

The attack took place at 9:25 a.m. as worshippers gathered at the Eidgah mosque for the start of the Muslim holiday of Eid al-Adha.

"More than half (of the fatalities) were members of the security service," Interior Ministry spokesman Sediq Sidiqui told Afghanistan's AIP news service.

The dead also included five children, the deputy governor of Faryab province, Abdul Sattar Barez, said.

Witnesses said the bombing coincided with the arrival at the mosque of a large number of national and regional officials.

No one claimed responsibility for the blast, though the Taliban often resort to suicide attacks in their struggle to drive foreign forces from Afghanistan.

The civilian death toll from the conflict in the first six months of the year was 1,145, down 15 percent from the same period last year, according to the U.N. Mission in Kabul.

Eid al-Adha is one of the most important holidays in the Islamic calendar. EFE
