The impoverished Pacific nation had rolled out the red carpet for visiting world leaders during the two-day conference, and even bought 40 Maseratis to ferry the dignitaries around.

"A group of policemen and soldiers are outside the parliament and demanding their APEC allowances," PNG police spokesman Dominic Kakas told AFP. He said that other police were "dealing with it".

No-one was known to be hurt, Kakas said, adding that he did not yet know how many police and soldiers were involved in the incident in the nation's capital Port Moresby.

A witness outside parliament told AFP "hundreds of police and troops" were standing on the front steps of parliament protesting that they had not been paid a special APEC allowance of 350 kina (US$104).

"The scene outside parliament is very tense. There are dozens of police cars and army vehicles," the witness said, adding that a nearby hotel was in lockdown and the protesters were blocking traffic.

Footage posted by PNG MP Bryan Kramer on Facebook showed smashed pot plants, photo frames knocked to the floor and broken glass and furniture near the parliament's entrance.

Some locals in PNG, the poorest member of APEC, had expressed anger with the government's lavish expense for the summit, which came at a time when the developing nation of eight million people is battling a polio outbreak and the resurgence of malaria, while struggling to pay its teachers.
