The ransackers were angry at alleged Pakistani border incursions

Khurshid Mahmood Kasuri told the BBC the mission would reopen when its computers had been repaired.

Mr Kasuri also said a telephone call between Afghan President Hamid Karzai and Pakistan counterpart Pervez Musharraf had cleared up all misunderstandings between the countries.

The attack occurred during a protest against alleged Pakistani incursions into Afghanistan.

Mr Karzai apologised to Islamabad for the attack after Pakistan lodged a formal complaint.

On Wednesday, Afghans trying to obtain visas and passports were being turned away from the closed mission by dozens of police.

'Out of context'

Mr Kasuri vowed that Pakistani embassy officials "would stay in the country".

"We've been assured that all necessary steps will be taken to ensure their security. I've spoken to the acting foreign minister in Kabul; he's apologised and said these [attackers] were people who didn't wish to see an improvement in Pakistan-Afghan relations," Mr Kasuri said.

Afghan hostility towards Pakistan had mounted over the weekend after General Musharraf allegedly spoke of a power vacuum in Afghanistan and apparently claimed the government did not represent all ethnic groups.

Afghan officials also accused Pakistan of sending troops into Afghan territory during operations on the border - a charge rejected by Pakistan.

Mr Kasuri said General Musharraf's comments had been taken out of context.

"In their telephone conversation, [General Musharraf] cleared all misunderstandings. He said [to Mr Karzai], 'I'll send you the text of my speech; I said nothing like this.'"

Mr Kasuri said reports that Pakistani forces had occupied an Afghan border post were "baseless".

"Our troops are on our side. On their side are personnel from both the Afghan and American forces."

In their telephone call, Mr Karzai told General Musharraf that those responsible for the attack were enemies of peace and promised to pay compensation for the damage.
