Afghan Transport Minister Inayatullah Qasmi told reporters on Wednesday that he supported Kabul's claims of Pakistan sponsoring Taliban attacks and providing militants refuge. Qasimi said the recent arrest of three Pakistanis for their alleged involvement in an assassination attempt on the US ambassador to Afghanistan was proof of Islamabad's involvement.He was talking to journalists after the handing-over ceremony of 23 buses to Afghanistan by Prime Minister's Finance Adviser Dr Salman Shah. Asked about his government's recent allegations that Osama Bin Laden and other top Al Qaeda members were hiding in Pakistan, the Afghan minister did not comment, saying he did not deal with such issues. "Terrorism needs to be stopped and both Afghanistan and Pakistan are committed to erasing this menace. Kabul wants greater economic ties with Islamabad and the boost in our economies will help increase employment, which would ultimately minimise terrorism in the region," said Qasimi, adding that his country was focusing on education and economy. He said that Pakistan's exports to Afghanistan touched $1b in 2004, with the trade balance favouring Pakistan. He said seven years ago, Pakistan's export was only US$ 30 million.
