Fugitive opposition leader Imran Khan surfaced at a student demonstration against emergency rule Wednesday. His party said he was promptly detained by security agencies, something authorities would not confirm. Some 200 students cheered wildly and lifted Khan into the air when he got out of a car on a university campus in the eastern city of Lahore. "Then some people came and took him away. He was on my shoulders when they grabbed him," said Faisal Naim, a student. Naim said he couldn't identify the men in plainclothes who hustled Khan into a nearby building.
