Major developments in the aftermath of Hurricane Katrina:

– Looting, carjacking and other violence spread in the Gulf Coast region, with even rescuers being attacks. The military expects to increase National Guard deployment to 30,000 from around the country to help with security, rescue and relief.

– The official death toll in Mississippi is 126 and rising. New Orleans mayor estimates the death toll in his city to be in the hundreds is not thousands. He pleaded for buses and supplies for survivors, saying, “This is a desperate SOS.”

– Half a day after the military began evacuating the Superdome, the arena held 10,000 more people than it did at dawn. Evacuees thinking it’s the best place to get a ride out of town pour into the Superdome and swelled the crowd to about 30,000.

– Frustration grows among the thousands still awaiting help at the New Orleans Convention Center, where bodies lie among the living. Earlier, helicopter transfers of the sick and injured at the Superdome were suspended amid security concerns.

– The state of Texas agrees to triple to 75,000 the number of evacuees being taken in from Louisiana. Some are being housed in Houston’s Astrodome, others are relocating to San Antonio or Dallas.

– President Bush plans to tour the region Friday. He warns against looting and price-gouging and asks his father, former President Bush, and former President Clinton to lead a fund-raising campaign for victims.

– The Bush administration intends to seek $10 billion to cover immediate relief needs, and lawmakers hope to approve the request by the weekend, congressional officials say.

– Gasoline supplies tighten in markets that depend on Gulf Coast refiners. As gas prices rise above $3 a gallon, some retailers are overrun by motorists wanting to beat further increases.
