KABUL, Oct 31 Afghan President Hamid Karzai secretly met three Taliban leaders two weeks ago in an effort to weaken the US-led coalition's most vicious enemy, a powerful Al Qaeda linked network that straddles the border region with Pakistan.

Held in Kabul, the meeting included a wanted former Taliban governor and an imprisoned militant who were flown to the capital from the Pakistani city of Peshawar, according to a former Afghan official.

The talks were not directly linked to the Afghan government's efforts to broker a peace with the Taliban and find a political solution to the rebellion. Rather, they were part of an effort to weaken the Haqqani network, the former official said over the weekend.

A western official, who spoke anonymously because he had no authority to discuss the talks, confirmed that a meeting between US-backed Karzai and Taliban figures had taken place, but did not know its full details or the names of all the participants.

Led by Jalaluddin Haqqani and controlled by his son, Sirajuddin, the network is thought to be responsible for most attacks against invading US troops in eastern Afghanistan and has been a key US military target. The network is linked to Al Qaeda and is believed to be sheltering its second-in-command, Ayman al-Zawahri.

Weakening the network would take the pressure off US forces and bolster Mr Karzai's efforts to broker some kind of peace with the Taliban in portions of the country.The Taliban resistance leaders who met with Mr Karzai are Maulvi Abdul Kabir, governor of the eastern Nangarhar province during Taliban rule and the current head of the Taliban's Peshawar council; his deputy governor in the Taliban regime, Sedre Azam; and Anwar-ul-Haq Mujahed, a militant leader from eastern Afghanistan credited with helping Osama bin Laden escape the US assault on Tora Bora in 2001, the former official said.

They spent two nights in the Afghan capital. Kabir is on the US most wanted list.

The men were brought by helicopter from Peshawar in Pakistan and driven into Kabul. Mr Mujahed has been in Pakistani custody since June last year when he was picked up in a raid in Peshawar, where one of several Afghan Taliban Shuras, or councils, is located.

They spent two nights at a heavily fortified hotel in the Afghan capital before returning to Peshawar by helicopter, where Mr Mujahed was placed again in custody. The US earlier this month acknowledged facilitating some Taliban trips to Kabul but provided no specifics. The Pakistani military has not commented on such reports.

The former Afghan official, who asked not to be named because of his relationship with both the government and the Taliban, described Mr Kabir and his associates as “midlevel” contacts because they have little, if any influence over the more powerful Quetta and Waziristan Shuras. Those two Shuras provide leadership for the majority of Taliban fighters in Afghanistan and are overseen by Taliban spiritual leader Mullah Mohammed Omar.

The Haqqani network straddles Pakistan's North Waziristan tribal area and the eastern Afghan provinces of Khost, Paktia and Paktika. The provinces' residents are mainly Pashtun, the majority ethnic group in Afghanistan that is the backbone of the Taliban.

But in Afghanistan, where power and strength are measured by tribal influence, Washington and Kabul are seeking to capitalise on Mr Kabir's position in eastern Afghanistan's powerful and dominant Zadran tribe. Both Mr Kabir and Mr Haqqani belong to the tribe.

The elderly Haqqani has drawn his strength from the Zadran tribe - estimated to number about 500,000 people - since the war with the Soviets in the 1980s. Outside the three eastern Afghan provinces, the Zadrans also dominate some small pockets in northwest Pakistan.

Both Washington and Mr Karzai want to try and sap some of Mr Haqqani's tribal-based strength by bringing Mr Kabir on board and dividing tribal loyalties, the Afghan official said.

Mr Karzai has formed a 70-member High Peace Council in an effort to try to reconcile with the Taliban and find a political solution to the rebellion. The Taliban deny that any of their representatives have been involved in talks. They claim their leaders will not discuss peace with the US-backed Afghan government unless invading foreign troops first leave Afghanistan.

US President Barack Obama's special envoy for Afghanistan and Pakistan, Richard Holbrooke, last week said news reports of extensive discussions between Afghan government officials and senior Taliban commanders were off base. He told journalists in Washington last week that there have been no such talks or discussions, let alone negotiations.

However, Mr Holbrooke did say that individuals who have fought alongside the Taliban - apparently not Taliban leaders themselves - have been reaching out. Mr Holbrooke mentioned no names but said those who are making such contacts are “provincial leaders, individual commanders”.
