Afghanistan, US still back Taliban talks KABUL and Washington have reaffirmed they seek peace with the Taliban despite attacks on a CIA base and the Afghan presidency. US President Barack Obama and Afghan President Hamid Karzai held a 90-minute conference call on Wednesday to revive early efforts to start peace talks. The level of violence still raging in Afghanistan was highlighted when the Taliban launched an assault Tuesday in the heart of Kabul in which three security guards and all five assailants were killed. Gunmen and bombers using fake NATO identification attacked an entrance to the Afghan presidential palace and a nearby building known to house a CIA base. Tentative steps towards talks were wrecked last week when a new Taliban office in Qatar provoked anger from Afghanistan and the US for styling itself as the embassy of a government-in-exile. Karzai refused to send representatives to Qatar and pulled out of separate talks on a security agreement with the US that would allow Washington to keep some troops in Afghanistan after 2014. Washington launched an intense diplomatic effort to pacify Karzai and dispatched US special envoy to Afghanistan and Pakistan, James Dobbins, for face to face talks. "Both presidents talked about the security agreement between Afghanistan and the US, the peace process and Taliban Qatar office," Karzai's office said in statement. The US president appeared to have persuaded Karzai to renew peace efforts after the Afghan leader's furious response to the Taliban's Qatar office opening under the formal name of the movement's hardline 1996-2001 regime. The two leaders agreed that "an Afghan-led and Afghan-owned peace and reconciliation process is the surest way to end violence and ensure lasting stability in Afghanistan and the region," the White House said. They reiterated their support for an office in Doha for the purpose of negotiations between the (Afghan government's) High Peace Council and authorised representatives of the Taliban. Dobbins said on Monday that Washington had also been "outraged" at how the Taliban opened the office, which had been intended to help foster a peace deal to end the decade-long war in Afghanistan. The Taliban hoisted the rebel group's white flag and referred to themselves as the 'Islamic Emirate Of Afghanistan'. The Afghan government insists the Taliban's office in the Gulf state must only be used for direct talks with Karzai's appointed negotiators.
