A bomb attack on a mosque in Afghanistan killed the governor of a province south of Kabul, a friend of the country’s president, yesterday during his address on the first day of the Muslim holiday of Eid al-Adha, officials said.

Arsala Jamal was governor of Logar province, a strategically important province on the southern approaches to Kabul and home to one of Afghanistan’s richest mines.

He had been governor of violence-plagued Khost pro-vince on the Pakistani border and the killing of such a senior official will raise new fears for Afghanistan’s security as foreign troops prepare to leave by the end of next year.

“When the governor was giving a speech it detonated. He is martyred,” said Jamal’s spokesman, Din Mohammad Darwish. He said one other person had been killed. No one claimed responsibility.

Jamal was a close friend of President Hamid Karzai and served as his campaign manager during his successful bid for re-election in 2009.

He survived at least one attempt on his life, when a suicide bomber in a car attacked him, killing his guards and a local official in 2007.

Darwish said the bomb was planted inside the mosque and detonated remotely. Police initially said a suicide bomber had been responsible.

A group supporting Afghanistan’s administrative development said it suspected Jamal’s work to get the Aynak copper mine in Logar province up and running was the reason he was killed.

“These activities were not acceptable to the enemies of the country and that’s why they martyred him,” the Independent Directorate of Local Governance agency said.
