Medan – A load of relief supplies slung under a US military helicopter fell and slammed into a car parked at a shopping mall in the Indonesian city of Medan early Wednesday, local officials said. Provincial government spokesman Eddy Sofyan said there were no injuries but that one car parked at the mall was damaged.

Sofyan said the North Sumatra provincial government wants US forces to stop transporting heavy loads of aid in nets hanging below helicopters. The US Navy was investigating and cooperating with local officials, said its spokesman Lt. Billy Ray Davis. It was not immediately clear if the Navy had changed the way it delivered aid.

The helicopter was delivering aid as part of a massive US military relief operation underway in tsunami and quake-hit regions of Indonesia.

More than 90,000 are confirmed dead on Sumatra island and up to a million people were made homeless by the December 26 quake and tsunami disaster.
