Pakistan ? The presidents of Pakistan and Afghanistan pledged during an unusually friendly meeting Wednesday to share intelligence and tighten border controls to quash rising militant attacks.

Talks between the two leaders – who frequently argue over the source of cross-border terrorism – came amid a wave of violence in Pakistan blamed on local Islamic extremists in the largely lawless border region.

A suicide bombing during a prayer service at a mosque Friday killed 56 people and an attack on a military convoy in the area Sunday killed nine.

“People from both the countries are suffering under the hands of extremism and terrorism,” Pakistan President Pervez Musharraf said at a joint evening news conference.

The violence has led to disputes between the two U.S. allies in the war on terror, with Afghan officials saying the militants are using bases inside Pakistan to orchestrate attacks against President Hamid Karzai’s government and Pakistan denying the accusation.
