About 3,000 tribesmen on Friday chanted "Allahu Akbar" (God is great) and "Death to America" while protesting against a raid by Afghanistan-based United States-led troops. One of the elders reportedly warned the US authorities to prepare for assaults on their bases in Afghanistan if they do not stop attacks on Pakistan's northwest border. "If Americans do not stop launching assaults in our tribal regions, we will attack their bases in Afghanistan," tribal elder Malik Ali Muhammad told the protesters. The rally took place in Wana, the main town in South Waziristan, where local officials said at least 15 people died in Wednesday's raid.
