Kabul, Taliban negotiators meet in Qatar as Afghan fighting rages
Taliban deputy negotiator Abbas Stanikzai and Afghanitan's former Vice-President Younus Qanooni.
The two sides have been meeting on and off for months in the Qatari capital, but the talks have lost momentum as the insurgents have made battlefield gains.
Several high-ranking officials, including former Afghan former chief executive Abdullah Abdullah, gathered in a luxury hotel on Saturday after morning prayers.
"The high level delegation is here to talk to both sides, guide them and support the (government) negotiating team in terms of speeding up the talks and have progress," said Najia Anwari, the spokeswoman for the Afghan government negotiating team in Doha.
- 'Ready for dialogue' -
"We are ready for dialogue, for talks and negotiations, and our priority is to solve the problems through dialogue," Taliban spokesman Muhamad Naeem told the Al Jazeera broadcaster ahead of Saturday's talks.
"The other side must have a true and sincere will to end the problems."
Pakistan on Saturday partially reopened its side of the southern border crossing with Afghanistan, shut after the Taliban seized control of the strategic Afghan frontier town of Spin Boldak from government forces last week.
Muhammad Tayyab, a local paramilitary official, said the decision was taken because of "relative calm on the other side", but that the crossing would remain closed to trade.
The Taliban have also tightened their grip on the north, with clashes continuing Saturday in the stronghold of infamous warlord Abdul Rashid Dostum, that borders Turkmenistan.
Also on Saturday, the French government flew out around 100 of its citizens and Afghans working for the embassy from the capital, as security deteriorated, a French diplomatic source said.
Several other countries including India, China, Germany and Canada have flown out their citizens or told them to leave in recent days.
- Taliban onslaught -
As fighting raged over large swathes of Afghanistan, a war of words was also heating up between Kabul and Islamabad, after the Afghan vice president accused the Pakistani military of providing "close air support to Taliban in certain areas".
Pakistan strongly denied the claim, with a foreign ministry statement saying the country "took necessary measures within its territory to safeguard our own troops and population".
Islamabad had touted a conference of regional leaders to address the spiralling violence.
Instead it announced it would delay the summit until after the Muslim Eid al-Adha feast, due to start next week at the end of the annual hajj pilgrimage, clearing the way for the Doha gathering.
Afghanistan's southern border has long been a flashpoint in relations with its eastern neighbour.
Foreign troops have been in Afghanistan for nearly two decades following the US-led invasion launched in the aftermath of the September 11 attacks.
They have appeared largely out of the picture in recent months, but fears are growing that Afghan forces will be overwhelmed without the vital air support they provide.
The speed and scale of the Taliban onslaught have caught many by surprise, with analysts saying it appears aimed at forcing the government to negotiate on the insurgents' terms or suffer complete military defeat.
