KABUL (Agencies) The Afghan government was holding secret talks with the Talibans No 2 when he was captured in Pakistan, and the arrest infuriated President Hamid Karzai, according to one of Karzais advisers. The detention of Mullah Abdul Ghani Baradar - second in the Taliban only to one-eyed Mullah Mohammed Omar - has raised new questions about whether the US is willing to back peace discussions with leaders who harboured the terrorists behind the Sept 11 attacks. Karzai was very angry when he heard that the Pakistanis had picked up Baradar with an assist from US intelligence, reported an American news agency quoting the adviser. Besides the ongoing talks, he said Baradar had given a green light to participating in a three-day peace jirga that Karzai is hosting next month. The adviser, who had knowledge of the peace talks, spoke on condition of anonymity because of their sensitivity. Other Afghan officials, including Abdul Ali Shamsi, security adviser to the governor of Helmand province, also confirmed talks between Baradar and the Afghan government. Several media reports have suggested that Baradar had been in touch with Karzai representatives, but these are the first details to emerge from the discussions. Far from expressing gratitude, members of Karzais administration were quick to accuse Pakistan of picking up Baradar either to sabotage or gain control of talks with the Taliban leaders. Meanwhile, Afghanistans government denied the report on Tuesday that it had been holding secret peace talks with Baradar. There was no direct contact between the government of Afghanistan and Mullah Baradar, Karzais spokesman Waheed Omer told reporters on Tuesday when asked about the latest reports. Karzai has occasionally used go-betweens without official status in preliminary efforts to reach out to militants. Omer said he was not aware of any such unofficial contact with Baradar, but fell short of denying it. I cannot confirm this, he said. I can only keep record of my government in contact with someone. Outside the government, I dont know. Last year, Karzais representatives reached out to some insurgents through Saudi Arabia for talks about talks, aimed at seeking a framework under which negotiations might be held. Karzai has invited Taliban who lay down arms to attend a peace conference in Kabul set for late April or early May. Omer said Karzais main focus since Baradar was arrested is persuading Pakistan to turn him over to Afghanistan. Afghan officials say Pakistan agreed to hand Baradar over, but a Pakistani court has ruled that he cannot be extradited.
