Al-Qaeda video shows US hostage pleading for his life My life is in your hands, Mr President. If you accept the demands, I live; if you don't accept the demands, then I die," the intelligence monitoring group Site quoted Mr Weinstein as saying in the latest video. In December, Ayman al-Zawahiri, the al-Qaeda leader, claimed to be holding Mr Weinstein and demanded an end to air strikes in Afghanistan, Pakistan, Somalia and Yemen, as well as the release of Osama bin Laden's relatives and other prisoners including the 1993 World Trade Center bombers. The new, undated video also includes a message for Mr Weinstein's wife. "I'm fine, I'm well, I'm getting all my medications, I'm being taken care of," he said Mr Weinstein, who suffers from asthma, heart problems and high blood pressure, was snatched after gunmen tricked their way into his Lahore home. He was country director for JE Austin Associates, which does contracting work with the US government's development agency, USAID. Pakistani security officials believe Weinstein is being held in Pakistan's lawless northwestern tribal belt, probably close to North Waziristan, which is the focus of US drone strikes targeting al-Qaeda and the Taliban. Informants have suggested he is moved regularly to avoid detection. Last month, the body of a British aid worker, Khalil Dale, was dumped in the south-west of the country, almost four months after he was kidnapped by unknown gunmen.
