FALLUJA, Iraq, March 17 (Reuters) - Two suicide truck bombers driving tanks filled with chlorine killed at least eight people and made 85 ill on Friday in the western Iraqi town of Falluja, hospital sources said on Saturday. The first attack was at the entrance of a housing complex, south of Falluja, that killed six people including policemen and sickened 79, including 27 children. The second bomber targeted a tribal leader opposed to al-Qaeda nearby when he blew up his tanker outside the man's home killing two and making six ill. Militants have used chlorine as a weapon in the past.
