A dozen homemade bombs exploded almost simultaneously Thursday morning at provincial government offices in Thailand's restive south, wounding six, police said.

Among the injured were three police officers and three civilians, said Boonyasit Suwanarat governor of Yala province. The explosions occurred in Thailand's three Muslim-dominated provinces, Yala, Narathiwat and Pattani, where an insurgency that started in 2004 has left more than 1,300 people dead.

The bombs exploded between 8:30 a.m. and 9 a.m. (0130 GMT and 200 GMT), as people were arriving for work.
