Governor Rick Perry says he's not aware of any specific terrorist threat against Texas, but Perry says state officials are taking Friday's heightened federal warning very seriously.
The Bush administration has raised the national terror alert from yellow to orange, the second-highest level in the color-coded system. US Attorney General John Ashcroft cited an "increased likelihood" that the al-Qaida terror network would attack Americans, either at home or abroad.
Perry says the State Emergency Operations Center in Austin was already activated due to last Saturday's shuttle "Columbia" tragedy. Perry says officials will notify state agencies, health institutions, schools and others to review their security measures and take appropriate actions to guard against terrorism.
Also under the heightened alert, U.S. Customs Officials increased security along the border between Texas and Mexico. Houston Mayor Lee Brown says major infrastructure, including airports, water treatment facilities and the Port of Houston already have heightened security after the terrorist attacks. Brown is encouraging everyone to stay vigilant.
Security is also being tightened at the nation's third busiest airport, Dallas-Fort Worth International. Officials Friday announced random vehicle searches will begin at the North and South entrances. DFW will also close about 13-hundred one-hour spaces that are closest to the terminals.
