Afghanistan ? The Taliban are moving fighters into Kandahar, planting bombs and plotting attacks as NATO and Afghan forces prepare for a summer showdown with insurgents, according to a Taliban commander with close ties to senior insurgent leaders.

NATO and Afghan forces are stepping up operations to push Taliban fighters out of the city, which was the Islamist movement’s headquarters during the years it ruled most of Afghanistan. The goal is to bolster the capability of the local government so that it can keep the Taliban from coming back.

The Taliban commander, who uses the pseudonym Mubeen, told The Associated Press that if military pressure on the insurgents becomes too great “we will just leave and come back after” the foreign forces leave.
