A female suicide bomber wearing an explosives blew herself up in a city north of Baghdad, wounding seven U.S. soldiers and five Iraqi civilians, the U.S. military said on Wednesday. 

And in Sri Lanka this morning, a female suicide bomber detonated herself at a government ministry in an assasination attempt. From the Associated Press:

On Wednesday morning, a suicide bomber blew herself up at Sri Lanka's social services ministry in the heart of Colombo in an unsuccessful attempt to kill the agency's minister, Douglas Devananda, who heads an ethnic Tamil party considered a rival to the rebels, the military said. 

On the subject of disguises and ruses that suicide bombers will use, nine Iraqi police were killed yesterday when a suicide bomber posing as a shepherd (complete with sheep) attacked a police checkpoint in Baquba. From Reuters:

Police at the Diyala province headquarters in Baquba, 65 km (40 miles) north of Baghdad, said they were taken by surprise when the suicide bomber herded several sheep towards a checkpoint before detonating a belt packed with explosives.

"There was nothing suspicious about him because it's an open, agricultural area and it's normal for shepherds to be around here," Diyala police lieutenant Ali Jassim told Reuters.
