A bomb placed inside a mosque in the country's east has reportedly killed the governor of Logar province.

According to the Associated Press, the Afghan officials said the explosion took place as Governor Arsallah Jamal was delivering a speech on Tuesday, Oct 15 morning to mark the Muslim holiday of Eid al-Adha.

The governor's spokesman, Din Mohammad Darwesh, said the bombing took place at the main mosque in the provincial capital of Puli Alam.

Provincial deputy police chief Rais Khan Abbul Rahimzai said the explosion also wounded 15 people, five of them critically.

No one immediately claimed responsibility for the attack but the Taliban have been targeting Afghan officials, military and NATO troops as part of a campaign to retake territory as international troops draw down ahead of a full pullout at the end of 2014.
