Pressure is building in the US to stop Turkey continuing its offensive against Kurdish-held areas in Syria.

Defence Secretary Mark Esper warned of "serious consequences" while Treasury Secretary Steven Mnuchin held out the prospect of fresh sanctions.

President Donald Trump's decision to withdraw US troops effectively triggered the Turkish incursion.

He has said he would like the US to negotiate a truce between Nato ally Turkey and the Kurds.

Turkish President Recep Tayyip Erdogan, however, says the military operation will continue. Kurdish leaders accuse the US of stabbing them in the back.

Meanwhile, the Pentagon said US forces near the town of Kobane - which were not included in the US withdrawal - had come under Turkish artillery fire on Friday evening.

According to the UN more than 100,000 people have fled their homes since the offensive began on Wednesday.

President Erdogan says he wants to create a "safe zone" in northern Syria free of Kurdish militias which could also be home to Syrian refugees.

One major concern for the international community is the fate of thousands of suspected IS prisoners, including many foreign nationals, being guarded by Kurdish-led forces in the region.

What happened to the US troops?

On Friday, the Pentagon said its base near the northern Syrian town of Kobane - an area known by Turkey to have US forces present - had seen shell fire from Turkish positions.

"All US troops are accounted for with no injuries," Navy Captain Brook DeWalt said in a statement. "The US demands that Turkey avoid actions that could result in immediate defensive action."

Turkey denied deliberately targeting US forces.

The Kurdish-led Syrian Democratic Forces (SDF) - a key US ally in the region - are facing numerous Turkish ground and air assaults along a stretch of the Turkey-Syria border about 75 miles (120km) long, correspondents say.

Dozens of fighters from the SDF and pro-Turkish factions have been killed. Turkey's military confirmed the first death of a Turkish soldier and said three others had been wounded.

At least 11 civilians have been killed and humanitarian groups say the number of people affected will rise.

What is the US now doing to pressure Turkey?

Defence Secretary Esper insisted that the US had not abandoned its Kurdish allies, despite the widespread view that the decision to withdraw US troops effectively triggered the Turkish incursion.

The official warned of unspecified "serious consequences" for Ankara if it did not halt the assault.

Mr Esper accused President Recep Tayyip Erdogan of taking "impulsive action" and warned that the operation "risks the security of ISIS (Islamic State) prison camps".

Treasury Secretary Steven Mnuchin said President Trump had authorised officials to draft what he called "very significant" new economic sanctions against Turkey.

"We can shut down the Turkish economy if we need to," he said.

President Trump spoke briefly about the situation as he prepared to head to a rally on Friday, saying: "We don't want them killing a lot of people... if we have to use sanctions we will."

Meanwhile in Congress, lawmakers from both sides of the political divide were preparing legislation to pile pressure on Turkey.

A bill to issue sanctions against Turkish officials and banks involved in the offensive was introduced by the Democratic chairman of the House of Representatives Foreign Affairs Committee, Eliot Engel, and the committee's ranking Republican Mike McCaul.

What has Turkey said?

"Now there are threats coming from left and right, telling us to stop this," President Erdogan said on Friday. "We will not step back."

He previously threatened to send some of the 3.6 million Syrian refugees it hosts to Europe if the offensive was described as an occupation.

What are the humanitarian fears?

According to aid workers on the ground, the vast majority of civilians have fled Tal Abyad and those who remain fear for their lives.

OCHA said the Turkish bombardment had affected key civilian infrastructure such as water stations. Thousands of people could lose adequate access to clean water in the Hassakeh region, it reports.
