BANGKOK - Authorities in Thailand investigated a series of bomb blasts that injured 13 people, including women and children, in the southern city of Hat Yai.
Seven bombs went off simultaneously Sunday night at restaurants and stores in the downtown business area, the Bangkok Post reports.
Most of the explosive devices were hidden in motorcycles and garbage cans but authorities say one bomb was thrown onto the grounds of a hotel.
Authorities were able to destroy one device before it exploded at a mall.
Hat Yai police believe the attacks were carried out by the same separatists who injured 70 people last September with a series of bomb blasts.
