The death toll from a 27-hour Taliban siege of Kandahar airport has jumped to 50, Afghan officials said Thursday, after a conference in Pakistan shored up international support for reviving peace talks.

The death toll from a 27-hour Taliban siege of Kandahar airport has jumped to 50, Afghan officials said Thursday, after a conference in Pakistan shored up international support for reviving peace talks.

Eleven suicide attackers on Tuesday breached the high-security complex which also houses a joint NATO-Afghan base, taking families hostage and triggering firefights with soldiers.

The raid, which saw militants blowing themselves up among civilians before Afghan troops secured the area, is seen as the most serious attack in 14 years of war on the complex, the largest military installation in the south of the country.

37 people, including 17 army men and four police, were wounded.

The Taliban posted a picture on their website of the terrorists it said were involved in the attack. It shows 10 young men sporting trimmed beards, Kalashnikovs and identical military uniforms.

The face of one of them is obscured with blue ink for unknown reasons.

The raid coincided with Afghan President Ghani's high-profile visit to Islamabad on Wednesday for the Heart of Asia conference aimed at promoting regional ties.

The Kandahar raid came after days of fevered speculation about the fate of new Taliban leader Mullah Akhtar Mansour following reports he was critically wounded in a firefight with his own commanders in Pakistan.
