Tow trucks hauled away the charred husks of buses Saturday, and a shortage of coffins was reported following nationwide riots that killed at least 300 people and left thousands injured.

Hospitals were crammed with victims of the four days of disturbances - the bloodiest in Venezuela's history.Authorities loosened a curfew in the capital and reduced the number of national guard units on the streets. Tow trucks cleared burned buses from intersections. Long lines of people stood outside distribution centers and the few food-stores open for business.

Residents near Caracas' central morgue said the smell of about 250 dead bodies was leading to fears of disease. News reports said some coffins were arriving with two bodies inside because there weren't enough caskets to go around.

The director of the largest hospital in the city said morgue officials called on medical officials to help them with the bodies.

The hospital director, Dr. Carmen Chirinos, said 1,881 injured people crowded her 700-bed Hospital Perez Car-reno. She said most of the injured were young men with bullet wounds.

"We've been doing very well under the circumstances," she said.

President Carlos Andres Perez said at least 300 people were killed and 2,000 injured in the riots and looting. News reports have said several thousand people were detained.

Insurance companies estimated damage to their clients was about $76 million but that many looted businesses had no coverage, according to news reports.

Authorities pushed back a 6 p.m. curfew to 8 p.m. Friday in Caracas and suspended it altogether in several regions of the country.

The military had airlifted 50 tons of food into Caracas in the last three days, news reports said.

Soldiers guarded vital roads, gasoline stations, food distribution centers and government buildings, but there were fewer armored personnel carriers and tanks in the streets.

However, many Caracas residents still were not convinced the violence was over.
