Prison warders in Papua New Guinea have foiled a break out attempt by 487 prisoners who had not been fed for two days.
More than half the inmates at Baisu jail outside Mount Hagen in PNG's Western Highlands province got past three lines of fencing and scaled the outer four-metre fence.
Warders fired warning shots and managed to herd the prisoners back into their cells.
No one one was hurt.
A dispute between two rival contractors supplying the prison is believed to have caused the food shortage.
The jail's commanding officer, Chief Superintendent Simon Sobaim, told PNG's The National newspaper it would have been the biggest break-out in the country's history.
