PORT MORESBY, Papua New Guinea (AP) — Rebel soldiers seized the military's headquarters Thursday and replaced Papua New Guinea's top defense official with their own leader, who gave Prime Minister Peter O'Neill a week to step aside for his ousted predecessor.
The self-proclaimed new leader of the country's defense forces, retired Col. Yaura Sasa, insisted he was not mounting a coup. But he warned that the military will take unspecified action unless O'Neill stands down and former prime minister Michael Somare, is reinstated, as the national Supreme Court ordered last month.
"Both Sir Michael Somare and O'Neill have seven days to implement the Supreme Court's orders to resolve the current political impasse or I will be forced to take actions to uphold the integrity of the Constitution," Sasa told reporters in Port Moresby.
The government called on Sasa and his supporters to surrender and said the mutiny did not have support from the broader military.
Deputy Prime Minister Belden Namah told reporters that about 30 soldiers were involved in the mutiny and 15 of them have been arrested. Namah said Sasa could be charged with treason, which carries the death sentence.
The new crisis comes during a turbulent period for the South Pacific's most populous island nation, where both O'Neill and Somare claim to be the rightful prime minister.
Rebel soldiers overpowered guards at the Taurama Barracks in Port Moresby before dawn. They then moved to the military headquarters at Murray Barracks and placed the head of the Papua New Guinea Defense Force, Brigadier General Francis Agwi, under house arrest. There were no reports of bloodshed.
Sasa, who last served as Papua New Guinea's defense attache to Indonesia before retiring from the military, told reporters he had been legitimately appointed defense chief by Somare.
Somare's spokeswoman Betha Somare told Australian Broadcasting Corp. that his ousted cabinet had confirmed Sasa's appointment several days ago. Betha Somare, who is also Michael Somare's daughter, did not immediately reply to The Associated Press' request for comment on Thursday.
Namah said Somare had "no sanity" and was using "rogue soldiers to pursue his own greed and selfishness."
O'Neill had told Australia — Papua New Guinea's former colonial master and main provider of foreign aid — that "authorities were taking steps to manage the situation," Australia's Department of Foreign Affairs and Trade said.
Somare was Papua New Guinea's first prime minister when it became independent in 1975, and was knighted by Britain's Queen Elizabeth II. Papua New Guinea's Parliament replaced him with O'Neill in August, while Somare was getting medical treatment outside the country.
Last month, the country's Supreme Court and Governor-General Michael Ogio backed Somare, who the court ruled was illegally removed. But Ogio changed his mind days later, saying bad legal advice had led him to incorrectly reinstate Somare.
Australia, which has the largest diplomatic mission of any country in Port Moresby, called for Agwi to be reinstated.
"We urge that the situation be resolved as soon as possible, and that the PNGDF chain of command is restored," the foreign affairs department said in a statement.
