President General Pervez Musharraf arrives in Kabul today (Wednesday) to tackle the tenacious problem of militants using the two countries. Musharraf will meet Afghan President Hamid Karzai, the Afghan Foreign Ministry said on Tuesday.Militants often cross the two countries' long, porous border. "Afghanistan is expecting Pakistan to take effective action against terrorism," said Afghan Foreign Ministry spokesman Sultan Ahmad Baheen. Musharraf will likely give Karzai evidence that individuals have used Afghan territory to destabilise Pakistan's Balochistan province, a Pakistani government official said on condition of anonymity. During Musharraf's visit, he will also inform Karzai of steps Pakistan has taken to curb militancy, drive Taliban and Al Qaeda remnants from border areas, and control weapons and drug smuggling, the official said.
