At least 6 dead in suicide attack at Afghan mosque

June 15 (UPI) -- Six people were killed and several others were injured in Afghanistan on Thursday in an explosion at a Kabul mosque, authorities said.

The explosion occurred at the Shiite Al-Zahra mosque in the Afghan capital Thursday evening, amid preparations for Lailatul-Qadr, a "night of power" observation held on the 19th, 21st and 23rd days of Ramadan.

Witnesses reported hearing gunfire after the explosion on Kabul's west flank, which security officials said appeared to be a suicide attack. At least ten people were reported injured in the blast.

Authorities described the bombing as a terrorist attack, BBC News reported.

Dozens were killed a year ago at another mosque attack in Kabul in a similar suicide bombing.
