SYRIA’S Kurds have accused the US of turning its back on its allies as American troops began pulling back from positions in north-eastern Syria ahead of an expected Turkish assault.

Syrian Kurdish fighters warned that Washington’s abrupt decision to stand aside – announced by the White House late on Sunday – will overturn years of achievements in the battle against militants from Daesh. They accused Washington of failing to abide by its commitments to its key allies.

There was no immediate confirmation from the White House of US troops clearing positions in areas in northern Syria.

However, Turkish president Recep Tayyip Erdogan (pictured with Donald Trump, right) also said American troops have started pulling back. The Kurdish news agency showed a convoy of American vehicles heading away from the border.

MEANWHILE, France’s interior minister has acknowledged that there was a breach in security that failed to detect signs of radicalisation of a police employee who killed four people inside Paris police headquarters.

Christophe Castaner told France Inter radio the attacker had previously “justified” the deadly 2015 Islamic extremist attack on satirical newspaper Charlie Hebdo in front of his colleagues, but no written report was made at the time. An internal investigation has been launched, in addition to the judicial investigation.

The longtime police employee stabbed four colleagues to death on Thursday before he was shot and killed. His wife was released from police custody on Sunday.

ELSEWHERE,Ukraine’s foreign minister said a planned pullback of forces in the rebel east has been delayed because of recent skirmishes.

Ukraine and Russia-backed separatist rebels had agreed to pull their forces from the front line in two areas to create a safe buffer zone.

But foreign minister Vadim Pristaiko (left) said the move has been postponed due to recent shelling by separatists.

More than 13,000 people have been killed in the five-year conflict between Ukrainian troops and Russia-backed rebels.
