Somali pirates hijacked a Thai cargo ship with 28 crew members onboard, the International Maritime Bureau said Friday, according to AP. Pirates attacked the Thor Star on Tuesday, senior analyst Cyrus Mody said, in the latest in a string of attacks in lawless Somali waters. Mody was unaware of any demands for ransom. The ship is owned by the Thor Star Shipping Company Limited and managed by Bangkok-based Thoresen and Company. The Gulf of Aden, where many of the attacks take place, connects the Red Sea and the Indian Ocean, forming one of the world's busiest shipping lanes. The attackers are usually armed with automatic weapons and rocket propelled grenades and travel in small, fast speedboats that can be towed more than a 100 miles (160 kilometers) offshore by a larger vessel to wait for their prey.
