Australia confirmed Thursday it will sign an asylum-seeker resettlement deal with Cambodia in a move slammed by human rights groups as violating the country's international obligations.

Immigration Minister Scott Morrison will be in Phnom Penh on Friday to seal the deal, which could see some asylum-seekers currently held in offshore detention camps by Australia transferred to the Southeast Asian nation.

Australia said Friday it has ordered a review into the medical care of an asylum-seeker who is reportedly on life support after cutting his foot at an offshore camp, as activists said he was the victim of neglect.

A volcano which has erupted in Papua New Guinea was Saturday spewing fragments from its crater and rumbling loudly, but its activity appeared to be subsiding, a seismologist said.

Australia's human rights commissioner said Thursday the government must come clean about conditions at offshore asylum-seeker camps after an inquiry heard of an alleged cover-up of mental health problems.

A strong 6.6-magnitude earthquake struck off Papua New Guinea in the Solomon Sea early Saturday, U.S. geologists said.

The offshore quake hit at 1:00 am (1500 GMT Friday) and occurred 193 kilometers (119 miles) south of Taron on PNG, according to the U.S. Geological Survey (USGS).

Australia announced further tough reforms to its asylum-seeker policy on Wednesday, saying refugees should have to prove a higher risk of danger than before to avoid being sent home.

Immigration Minister Scott Morrison said the changes would also put the onus on asylum-seekers to prove their claims, while visas would be denied to people who threw away their documents.

Australia's highest court Wednesday dismissed a challenge to the government's policy of sending asylum-seekers to Papua New Guinea, ruling detention at an island immigration camp legal.

An Iranian who arrived at Australia's Indian Ocean territory of Christmas Island by boat in July 2013 brought the case after he was transferred to PNG's Manus Island.

Families of asylum-seekers killed in a shipwreck off Australia's Christmas Island in 2010 are suing the government, arguing it breached its duty of care in a move Canberra Tuesday blasted as "shameful".

Fifty people died when a rickety fishing boat crowded with nearly 100 Iraqi, Kurdish and Iranian asylum-seekers was dashed against jagged rocks in dangerous seas at the remote Indian Ocean outpost.

Papua New Guinea's anti-corruption watchdog issued a warrant on Monday for the arrest of Prime Minister Peter O'Neill, reports said.

The warrant relates to allegations that O'Neill personally authorised the illegal payment of millions of dollars from the government to law firm Paul Paraka Lawyers, the Australian Broadcasting Corporation (ABC) said.

Two Indonesian nationals were Thursday sentenced to six and nine years in jail in Australia for people-smuggling, after a doomed venture in which more than 100 people drowned.

The men were not charged with organizing the people-smuggling venture or with the deaths of any passengers who perished when the boat sank off Christmas Island in June 2012.
