From the mastermind behind the underwear bomb, US officials now fear a new couture-based weapon: clothes dipped in liquid explosives. ABC News says senior government officials heard about the potential new threat at a briefing on yesterday's embassy closures. Two officials present at the meeting say the explosive clothes would be undetectable by current security measures. "It's ingenious," says one of them.
The technique is believed to have been developed by Ibrahim al-Asiri, who is also thought to be behind "body bombs." Al-Asiri, a member of al-Qaeda affiliate al-Qaeda in the Arabian Peninsula, is one of 25 people named by the Yemeni government today as the country's top terrorists. The government has put a bounty of $23,000 for any information leading to any of their arrests. (Read more al-Qaeda in the Arabian Peninsula stories.)
