Man killed

The region's president and police chief have called for people not to take the law into their own hands.

New Dawn FM reported dozens of houses were burnt and police cars stoned following the killing of a man on Sohano Island on Friday night.

Sebastin Siperau is reported to have died in a confrontation over money.

Police reported his relatives and friends then attacked a compound on Sohano and burnt 34 houses in the early hours of Saturday.

There were also reports some relatives went to the main town of Buka, to avenge the death.

It said the man approached the White House's fence on Pennsylvania Avenue just before noon local time (17:00GMT) before taking out a handgun and firing several shots.

No one else was injured, according to police.

President Donald Trump is not at the White House, but at his Mar-a-Lago estate in Florida.

The man was in a large crowd when he fired the gun, the Washington Post reports, citing witnesses.

A video posted to Twitter shows many people running away from the scene.

The man's name has not been released.
