KABUL: Foreign military officials raised the death toll in a 19-hour siege in Kabul to 11 on Wednesday as the Afghan government announced the violence had come to an end with the killing of two insurgents.

The attacks started on Tuesday but dragged into a second day as armed men remained holed up in a high-rise construction site overlooking the US embassy and the headquarters of the NATO-led International Security Assistance Force (ISAF).

Lieutenant Colonel Jimmie Cummings, an ISAF spokesman, said six foreign troops had also been injured.

"Nineteen (were) wounded, 11 killed, which includes three children," Cummings said, without giving immediate exact details of who the dead and wounded were.

"We also have six (ISAF) wounded in action since yesterday. Three of them were US which happened during the main engagement off the ISAF compound... the other three were in support during clearing (of the main building.)"

The death toll of 11 covered the main attack plus several much smaller related ones which took place elsewhere in Kabul on Tuesday.

Meanwhile, Afghan interior ministry spokesman Siddiq Siddiqui said the siege, which has raised fresh serious questions about security in Kabul, was now over.

"The last attackers are dead and the fighting all over. There were six terrorists in the building and all are dead," he said.
