Konar is a volatile province where militants regular cross the border from Pakistan's Northwest Frontier Province. U.S. and Afghan troops often clash with pro-Taliban militants there.
This is not the first time Karzai has accused Pakistan of interfering in Afghan affairs.
Pakistan's President Pervez Musharraf recently accused Karzai of being "oblivious" of what is happening in his own country. He said Karzai has provided Pakistani intelligence services with outdated information about Islamic militants.
