Several thousand Syrian Kurds began crossing into Turkey on Friday fleeing ISIL fighters who advanced into their villages, prompting warnings of massacres from Kurdish leaders.

ISIL (IS) fighters have seized villages in northern Syria over the past two days and are besieging the mainly Kurdish town of Ayn al-Arab, known as Kobani in Kurdish, on the Turkish border.

Turkey is already sheltering more than 1.3 million Syrian refugees and fears hundreds of thousands more, waiting in the mountains on the Syrian side of the 900-km (560-mile) border, could seek to cross as fighting escalates.

The Syrian Observatory for Human Rights, which tracks developments in the civil war, said on Friday IS had seized three more villages near Kobani, bringing to 24 the number it had taken.

The attack on Kobani prompted a Kurdish militant call to the youth of Turkey's mainly Kurdish southeast to join the fight against IS and came days after the U.S. military said the help of Syrian Kurds would be needed against the militants.

Turkish Prime Minister Ahmet Davutoglu, who has said the priority is to give aid on the Syrian side of the border, said he had given the order for the Syrians to be let in after receiving information that 4,000 had arrived seeking shelter.

"When our brothers from Syria and elsewhere arrive at our borders to escape death ... without discrimination over religion or sect, we take them in and we will continue to take them in," he told reporters during a trip to Azerbaijan.

Turkey is trying to persuade the United States of the need to create a "buffer zone" inside Syria, Turkish officials said, a safe haven on the border likely to require a foreign-patrolled no-fly zone where displaced civilians could be given aid.

"The establishment of a buffer zone is of great importance both for Turkey and for Syrians who have been uprooted," a senior government official told Reuters, referring to an idea mooted this week by President Tayyip Erdogan.

Talks with U.S. officials were continuing, he said.

The president of Iraq's Kurdistan region urged the international community on Friday to "use every means" to protect the city of Kobani in neighbouring Syria.

"I call on the international community to use every means as soon as possible to protect Kobani," President Masoud Barzani said in a statement.

BREAD, WATER

The United States is conducting air strikes against ISIL in Iraq and last month Obama authorised surveillance flights over Syria.

Turkish soldiers armed with rifles initially formed a line along the border to maintain security, but allowed residents of the Turkish village of Dikmetas, 20 km (12 miles) along the frontier from Kobani, to fling bottles of water and bags of bread across a barbed wire barrier to the crowd of Syrian Kurds.

The soldiers later began escorting hundreds of mostly women and children, laden with possessions, into Turkey.

Machinegun fire and shelling could be heard from a few kilometres away and one woman brought across the border was hospitalised after stepping on a landmine.

Turkish security forces at one point fired tear gas and water cannon to disperse a group of about 100 people as they sought to cross into Syria on Friday in an apparent protest against the tight border security.

Turkey has maintained an open border with Syria throughout its conflict to allow refugees out and humanitarian aid in, but has tightened border security in recent months amid criticism that the policy enabled foreign fighters to cross and swell the ranks of ISIL militants.

The number of Kurds on the border shrank from about 3,000 on Thursday night, but more began arriving on foot on Friday.

"The weather was cold overnight so most went back to their villages. They started coming back to the border this morning," said Halil, a man in his 40s on the Turkish side of the border.

Western states have expanded contact with the main Syrian Kurdish party, the PYD, since ISIL seized wide areas of Iraq in June.

The YPG, the main Kurdish armed group in Syria, says it has 50,000 fighters and should be a natural partner in a coalition the United States is trying to assemble to fight ISIL.

But the Syrian Kurds' relationship with the West is complicated by their ties to the Kurdistan Workers' Party (PKK), a group listed as a terrorist organisation in many Western states because of the militant campaign it waged in Turkey.
