Taleban leader Mullah Mohammed Omar would refuse any offer of an amnesty from the Afghan government, a Taleban spokesman is reported as saying.

"We don't need any guarantee of safety," Taleban spokesman Abdul Latif Hakimi told the Reuters news agency.

On Monday the head of Afghanistan's reconciliation commission called on Mullah Omar to be included in an amnesty for Taleban fighters.

Mullah Omar has been in hiding since the fall of the Taleban in 2001.

'More attacks'

Mr Hakimi was in defiant mood when he spoke to Reuters.

"On [Mullah Omar's] orders, we have increased attacks on US forces in recent weeks and will continue this," he said.

The US military says scores of Taliban members have been killed in the last seven days as well as two US soldiers and a number of Afghan soldiers.

The government has been running an amnesty programme for Taleban fighters but it excludes senior figures or those guilty of what are deemed to be serious abuses of human rights.
