The World Food Program says it has flown its final aid flight to Burma's cyclone-ravaged Irrawaddy Delta.

A statement from the group says the flight took off Friday from Bangkok's Don Mueang airport. The airport has served as a staging point for sending supplies to Burma since the country's military-rulers first allowed foreign aid flights in late May, weeks after the storm hit.

Cyclone Nargis hit Burma on May 2 and 3, leaving at least 134,000 people dead or missing as it tore across the country's agricultural belt.

The WFP says that since its flights began on May 24, it has flown nearly 4,000 tons of cargo to Burma, including shelter material, mosquito nets and water purification equipment.
