Pakistani President Pervez Musharraf and his Afghan counterpart Hamid Karzai arrived here on Sunday for talks on tackling the Taliban-led insurgency, news agency Anatolia reported.

The two men were due to attend a dinner later on Sunday hosted by Turkish President Ahmet Necdet Sezer followed by a formal round of talks on Monday.

The summit is meant to ease tensions between the two leaders amid mutual allegations over the growing extremist violence on both sides of their shared 2,400 kilometre (1,500-mile) border.

The Taliban movement was toppled from government in Afghanistan more than five years ago but is waging an insurgency that is supported by other Islamic extremists.

Karzai has been joined by some Western figures in accusing Islamabad of not doing enough to round up Taliban and Al-Qaeda leaders living in Pakistan and crack down on extremist groups training and funding militants.

Islamabad meanwhile says it has taken effective measures and accuses Afghanistan of shifting the blame onto Pakistan for its own failures.

Some reports had earlier suggested Musharraf could return home after a suicide bomber killed 28 people and wounded Interior Minister Aftab Sherpao at a political rally in northwest Pakistan on Saturday.
