Bangladeshi forces stormed an upscale Dhaka restaurant where heavily armed militants held dozens of people hostage Saturday morning, killing at least six of the attackers and rescuing 13 captives including foreigners at the end of the 10-hour standoff. Seven Japanese are unaccounted for. About 35 people were taken hostage, including about 20 foreigners, when gunmen stormed the Holey Artisan Bakery in Dhaka's Gulshan area, a diplomatic zone, on Friday night. "We have gunned down at least six terrorists and the main building is cleared but the operation is still going on," Lt. Col. Tuhin Mohammad Masud, commander of the Rapid Action Battalion, told The Associated Press three hours after the commandos launched the rescue operation.
