Karzai, Musharraf unite on terror

A statement said that the leaders "reiterated their common commitment to fight terrorism". Karzai is on a two-day trip to Pakistan ahead of his own presidential elections in October.

On Tuesday he abruptly cancelled a speech to a state-run think tank citing "other engagements". Officials denied security was a reason for the decision to pull-out of the address to diplomats, officials and journalists.

"President Hamid Karzai's talk at the Institute of Strategic Studies was called off at the request of Afghan officials," Pakistani foreign ministry spokesman Masood Khan said. "There was no security threat."

A leading concern of the two nations is the fight against al-Qaeda remnants and the Taleban. "Anybody trying to carry out terrorist activities in Afghanistan or to disrupt election process or to create law and order problems will not be allowed from Pakistan - we will act against them," Musharraf said on Monday.

Karzai said Pakistan and Afghanistan had a "common commitment to stamp out terrorism", the state-run Associated Press of Pakistan reported.
