Dohuk (Iraq) (AFP) - Time was running out for starving Yazidis trapped on an Iraqi mountain Wednesday as the West ramped up efforts to assist survivors and arm Kurdish forces battling jihadists.
The United States has carried out air strikes against members of the Islamic State (IS) jihadist group in the area of Mount Sinjar, where the UN refugee agency says 20,000-30,000 people, many of them members of the Yazidi minority, are besieged.
Thousands more poured across a bridge into camps in Iraq's autonomous Kurdish region on Wednesday after trekking into Syria to escape, most with nothing but the clothes they wore.
Some women carried exhausted children, weeping as they arrived to the relative safety of Iraqi Kurdistan.
But there are still large numbers on the mountain, said 45-year-old Mahmud Bakr.
"My father Khalaf is 70 years old -- he cannot make this journey," he told AFP when he crossed back into Iraq.
UN minority rights expert Rita Izsak has warned they face "a mass atrocity and potential genocide within days or hours".
The displaced who managed to flee a siege that began 10 days ago found relative security in Kurdistan but complained that their living conditions had hardly improved.
"We were besieged for 10 days in the mountain. The whole world is talking about us but we did not get any real help," said Khodhr Hussein. "We went from hunger in Sinjar to hunger in this camp."
US Secretary of State John Kerry said Wednesday that Washington is looking at options to bring the trapped civilians out.
"We will make a very rapid and critical assessment because we understand it is urgent to try to move those people off the mountains," he said.
- More US military advisors -
Washington has already said it would ship weapons to the cash-strapped Kurds and on Wednesday France followed in US footsteps.
"The president has decided, in agreement with Baghdad, to deliver arms in the coming hours," President Francois Hollande's office said.
Defence Secretary Chuck Hagel said the United States has sent 130 more military advisors to northern Iraq to assess the scope of the humanitarian crisis.
A US defence official said the temporary additional personnel would also develop humanitarian assistance options beyond the current airdrop effort in support of the displaced civilians trapped on Mount Sinjar.
Britain said it has agreed to transport military supplies for the Kurdish forces from "other contributing states".
Australian Prime Minister Tony Abbott said Wednesday his country would join humanitarian airdrops in Iraq, and did not rule out the possibility of greater military involvement.
Washington has urged Iraqi premier designate Haidar al-Abadi to rapidly form a broad-based government able to unite Iraqis in the fight against jihadist-led insurgents who have overrun swathes of the country.
Abadi came from behind in an acrimonious process to select Iraq's new premier when President Fuad Masum on Monday accepted his nomination and tasked him with forming a government.
He has 30 days to build a team which will face the daunting task of defusing sectarian tensions and, in the words of US President Barack Obama, convincing the Sunni Arab minority that IS "is not the only game in town".
- Maliki yet to quit -
On Wednesday, Maliki continued to defy international pressure to step aside, declaring that it would take a federal court ruling for him to quit.
"I confirm that the government will continue and there will not be a replacement for it without a decision from the federal court," Maliki said in his televised weekly address.
The two-term premier has accused Masum of violating the constitution by approving Abadi's nomination, and vowed he would sue.
But the prospects of Maliki -- who told AFP in 2011 that he would not seek a third term -- succeeding in his quest to cling to power appear dim.
Whatever ruling the court might deliver, analysts say Maliki has lost too much backing to stay in power.
International support has poured in for Abadi, including from both Washington and Tehran, the two main foreign power-brokers in Iraq.
The political transition comes at a time of crisis for Iraq.
After seizing the main northern city of Mosul in early June and sweeping through much of the Sunni heartland, jihadist militants bristling with US-made military equipment they captured from retreating Iraqi troops launched another onslaught this month.
They attacked Christian, Yazidi, Turkmen and Shabak minorities west, north and east of Mosul, sparking a mass exodus that sent the number of people displaced in Iraq this year soaring.
A week of devastating gains saw the IS jihadists take the country's largest dam and advance to within striking distance of the autonomous Kurdish region.
US strikes and cross-border Kurdish cooperation have since yielded early results on several fronts, with Kurdish troops beginning to claw back lost ground.
