Four attackers launched an assault on the governor's compound in Afghanistan's western Farah province on Thursday and were shot dead in a firefight, an official said.

“Four suicide attackers who stormed the governor's compound exchanged gunfire with the police. All four attackers were killed by the police. There were no casualties among police or civilians,” the governor's spokesman Naqeebullah Farahi told AFP.

In a similar attack on the governor's office in Paktika province in southeastern Afghanistan a week ago, four people were killed and five wounded by a group of six suicide bombers wearing police uniforms.

Taliban insurgents seeking to topple the government of President Hamid Karzai claimed responsibility for that attack.

The attacks come in the wake of the Taliban announcing their spring offensive earlier this month, a campaign of bombings and attacks that picks up every year as the weather conditions improve. - AFP
