Akcakale, Oct 10 (AP) Turkey pressed its assault against US-allied Kurdish forces in northern Syria on Thursday for a second day, pounding the region with airstrikes and an artillery bombardment that raised columns of black smoke in a border town and sent panicked civilians scrambling to get out.

Residents fled with their belongings loaded into cars, pickup trucks and motorcycle rickshaws, while others escaped on foot. The UN refugee agency said tens of thousands were on the move, and aid agencies warned that nearly a half-million people near the border were at risk.

It was a wrenchingly familiar scene for many who had fled the militants of the Islamic State group only a few years ago.

The Turkish air and ground assault was launched three days after U.S. President Donald Trump opened the way by pulling American troops from their positions near the border alongside their Kurdish allies.

At a time when Trump faces an impeachment inquiry, the move drew swift criticism from Republicans and Democrats in Congress, along with many national defense experts, who say it has endangered not only the Kurds and regional stability but US credibility as well.

The Syrian Kurdish militia was the only US ally in the campaign that brought down the Islamic State group in Syria.

Trump warned Turkey for moderation during its assault and safeguard civilians. But the opening barrage showed little sign of holding back: The Turkish Defense Military said its jets and artillery had struck 181 targets so far.

More than a dozen columns of thick smoke rose in and around the town of Tel Abyad, one of the offensive's first main targets.

Turkish officials said the Kurdish militia has fired dozens of mortars into Turkish border towns the past two days, including Akcakale.

Turkish officials in two border provinces said mortar fire from Syria killed at least six civilians, including a 9-month-old boy and three girls under 15. On the Syrian side, seven civilians and eight Kurdish fighters have been killed since the operation began, according to activists in Syria.

A Kurdish-led group and Syrian activists said that despite the bombardment, Turkish troops had not made much progress on several fronts they had opened. But their claims could not be independently verified.

Turkish President Recep Tayyip Erdogan said 109 "terrorists" were killed in the offensive, a reference to the Syrian Kurdish fighters. He did not elaborate, and reports from the area did not indicate anything remotely close to such a large number of casualties. Erdogan also warned the European Union not to call Ankara's incursion into Syria an "invasion."

He threatened, as he has in the past, to "open the gates" and let Syrian refugees flood into Europe.

Turkish Foreign Minister Mevlut Cavusoglu said the military intends to move 30 kilometers (19 miles) into northern Syria and that its operation will last until all "terrorists are neutralized."

Meanwhile, the Kurdish forces halted all operations against IS in order to focus on fighting Turkish troops, Kurdish and U.S. officials said.

The Syrian Kurdish fighters, along with U.S. troops, have been involved in mopping-up operations against IS fighters still holed up in the desert after their territorial hold was toppled earlier this year.

Ankara considers members of the Kurdish militia to be "terrorists" because of their links to the outlawed Kurdistan Workers' Party, or PKK, which has led an insurgency against Turkey for 35 years.

The conflict has killed tens of thousands of people. The U.S. and other Western countries also consider the PKK a terrorist group.

Turkey, a NATO member, considers its operations against the Kurdish militia in Syria a matter of its own survival, and it also insists it won't tolerate the virtual self-rule that the Kurds succeeded in carving out in northern Syria along the border.

The Turkish assault aims to carve out a corridor of control along the length of the border — a so-called "safe zone" — clearing out the Kurdish militia. Such a zone would end the Kurds' autonomy in the area and put much of their population under Turkish control. Ankara has said it aims to settle 2 million Syrian refugees, who are mainly Arabs, in the zone.

Turkey began its offensive in northern Syria on Wednesday with airstrikes and artillery shelling, and then ground troops crossed the border later in the day.

Mustafa Bali, a spokesman for the Kurdish-led Syrian Democratic Forces, said their fighters have repelled Turkish forces ground attacks.

"No advance as of now," he tweeted Thursday. AP
