The presidents of Pakistan, Pervez Musharraf, and Uzbekistan, Islam Karimov, have signed an agreement in Tashkent on fighting terrorism.

President Pervez Musharraf arrived in the Uzbek capital early Sunday for a two-day visit. General Musharraf says he has assured President Islam Karimov that he will take action against any insurgents from Uzbekistan who try to operate in Pakistani territory.

President Musharraf's comments were taken as a signal that Pakistan would be willing to hand over to Uzbekistan any Uzbek militants it may detain. He told reporters in Tashkent that Pakistan and Uzbekistan should have a formal extradition treaty.

Suicidal attacks by Uzbek militants killed more than 50 people last year. Authorities in Tashkent have blamed the incidents on radical Islamic groups operating from Pakistan.

Mr. Musharraf says Pakistan is interested in joining the Shanghai Cooperation Organization, a regional security grouping that includes China, Kazakhstan, Kyrgyzstan, Russia, Tajikistan and Uzbekistan.

The Pakistani leader will head to Kyrgyzstan Monday for talks with President Askar Akayev.
