Pakistani Prime Minister Yousuf Raza Gilani and Afghan President Hamid Karzai have agreed to intensify both countries' campaign against the Taliban. The two leaders met in the Afghan capital Kabul, where Mr. Gilani was accompanied by military and intelligence chiefs. The Pakistani leader and Mr. Karzai agreed to upgrade a joint peace commission to coordinate the fight against Taliban-led insurgents, in an agreement Mr. Gilani described as “historical”. The announcement came just hours after a Taliban suicide attack on a military base near the eastern Afghan city of Jalalabad killed up to 10 Afghan and coalition soldiers. It was the latest in a series of attacks on police and army targets in the past week. Pakistan, which backed the Taliban government that ruled Afghanistan during the 1990s, will be crucial to any attempts to stabilize its western neighbour, although the two countries have had an uneasy relationship. Islamabad's intelligence services are still believed to have close links with many of the insurgent groups they funded and supported during and after the war against the Soviet Union, including the Taliban leadership based in Quetta. Afghan government officials have frequently accused Pakistan's military and its spy agency of trying to derail peace negotiations with Taliban leaders.
