Pakistani troops shut down three FM radio stations Friday after the stations aired a speech by a pro-Taliban cleric. The military said it confiscated a large quantity of illegal arms, ammunition, audio cassettes, and what it described as "provocative literature." At least seven suspected militants who worked at the stations were arrested. The raids took place in Pakistan's Swat Valley, a restive resort area in Pakistan's northwest. On Thursday, the stations had broadcast a recording of a fiery speech by Maulana Fazlullah, a radical Muslim cleric who has tried to enforce Taliban-style Islam in Swat. Pakistan's security forces have been battling Fazlullah's supporters since last year.
