Myanmar's military government has agreed to allow a limited amount of aid to be delivered by United States military planes.

The relief supplies will be delivered to the capital Rangoon.

US diplomats in the region say an initial C-130 plane will airlift at least one aid shipment, although the details are still being worked out.

It is also believed four UN officials from the disaster assessment coordination team are also to be given access.

The regime has been refusing to open up for most international relief operations despite the scale of death and destruction caused by the Cyclone Nargis.
