At least 12 people, including five Army soldiers, have died in Texas due to torrential rain in the past week which has also damaged hundreds of homes and led the state to evacuate three prison facilities, officials said on Friday, according to Reuters. The U.S. Army and local rescue teams were using boats, helicopters and sniffer dogs to search for four soldiers who went missing when their military vehicle overturned in a flood-swollen creek on Thursday at Fort Hood in central Texas. Five other soldiers in the vehicle were killed while three more who survived were expected to be released from a hospital as early as Friday, a military official told a news conference. The Texas Department of Criminal Justice began evacuating on Friday about 1,700 inmates at its Ramsey Unit in Rosharon, about 30 miles (50 km) south of Houston, due to flooding along the Brazos River. It evacuated about 2,600 inmates from two other facilities earlier this week due to flooding on the same river. Many of the inmates were sent to other units with available beds, it said. The National Weather Service has placed large parts of Texas and Louisiana on a flash flood watch, including Houston and New Orleans.
