A phone call between US President Donald Trump and Australian PM Malcolm Turnbull has called into question a refugee resettlement deal.
The Washington Post reported Mr Trump called the conversation "the worst by far" of his calls with world leaders that day, and cut it short.
Mr Trump later tweeted that he would "study this dumb deal".
Struck with the Obama administration, it would see up to 1,250 asylum seekers to Australia resettled in the US.
Australia has controversially refused to accept them and instead holds them on offshore detention centres on the Pacific nations of Nauru and Papua New Guinea.
PM Turnbull had been seeking clarification on the future of the deal after Mr Trump last Friday signed an executive order temporarily barring the entry into the US of refugees and people from seven Muslim-majority countries.
What do we know about the phone call?The phone call between Mr Trump and Mr Turnbull took place at the weekend, and was one of four the US president had with world leaders, including Russia's Vladimir Putin.
The Washington Post quotes senior US officials, briefed on the call, as saying that the conversation should have lasted an hour but was abruptly ended after 25 minutes by Mr Trump.
Mr Trump reportedly said accepting the refugees, many of whom are from Iran, Iraq and Syria, would be like the US accepting "the next Boston bombers", who were from the Caucasus region of Russia.
The official version of the call from the US was more restrained.
On Monday Mr Turnbull said he had spoken to Mr Trump and thanked him for agreeing to uphold the deal.
US presidential spokesman Sean Spicer also said Mr Trump intended to uphold the deal.
But Mr Trump's tweet on Wednesday - coming after the Washington Post story - has thrown fresh doubt on the deal.
Mr Turnbull later said he was disappointed that details of the call - which he described as "very frank and forthright" - had been made public.
He told a Sydney radio station that "the report that the president hung up is not correct".
What is the deal about?Australia announced in November 2016 that the US had agreed to a one-off deal to resettle refugees currently being held in its offshore detention camps in the Pacific nation of Nauru and Manus Island, in Papua New Guinea (PNG).
The UN refugee agency, UNHCR, would oversee the deal and the "most vulnerable" would be prioritised, Mr Turnbull said.
No numbers were given and Australian Immigration Department Secretary Mike Pezzullo later told a Senate inquiry that, while those who were eligible could express an interest, it was up to the US to decide how many people it wanted to take.
A total of 1,254 people were being held in the two camps, 871 on Manus Island and 383 in Nauru, as of 30 November 2016, according to Australian government statistics.
Mr Trump's tweet incorrectly labelled refugees as illegal, and recast the number who might be resettled as "thousands".
Australia refuses to accept refugees who arrive by boat, under a tough deterrent policy. It has already struck resettlement deals with Cambodia and PNG, but only a handful of refugees have been resettled. Critics say the two nations are completely ill-equipped to resettle refugees.
So the US deal was a boon to the Australian government, which has faced fierce international criticism for its offshore detention policy and which wants to close the Manus Island camp. Conditions in the offshore camps have been roundly condemned by rights groups, who say the policy is punitive and inflicts harm on refugees.
