The US has criticised Turkey for launching attacks on Syrian rebel groups - saying its efforts should instead be focussed on defeating Isis extremists.
Turkish-backed forces pushed deeper into northern Syria on Monday, the latest move in a two-week offensive. Reports suggested that at the start of the operation, Turkish forces were targeting Isis, but had since turned their efforts to attacking the Syrian Democratic Forces (SDF), a coalition that encompasses the Kurdish YPG militia. This coalition is being supported and backed by Washington in its efforts to counter Isis.
The developments underscore the complex and chaotic situation on the ground in Turkey, where dozens of factions and groups are vying for influence as a civil war rages. While both agreeing to coordinate efforts against Isis, the US and Russia are on opposing sides of the civil war, in which President Bashar Al-Assad is fighting to retain power.
Reuters reported that the US condemned those clashes between Turkish forces and opposition groups in northern Syria as unacceptable and called on all armed groups to stand down and focus on the fight against Islamic State.
“We want to make clear that we find these clashes - in areas where Isis is not located - unacceptable and a source of deep concern,” Brett McGurk, the special presidential envoy for the coalition to counter Isis, said on his official Twitter account.
“We call on all armed actors to stand down the US is actively engaged to facilitate such deconfliction and unity of focus on Isis, which remains a lethal and common threat.”
Turkish officials say their goal in Syria is to drive out Isis, but also to ensure Kurdish militia fighters do not expand the territory they already control along Turkey’s border.
Turkey and its own Syrian rebel allies seized territory controlled by Kurdish-aligned forces on Sunday, the fifth day of a cross-border campaign that a monitoring group said had killed at least 35 villagers.
The Kurdish YPG fighters are backed by the United States in the fight against Islamic State in Syria, the Associated Press said. However, NATO member Turkey sees the YPG as an extension of the outlawed Kurdistan Workers Party (PKK), which has waged a three-decade insurgency in Turkey's largely Kurdish southeast.
The differing priorities puts Ankara at odds with Washington and adds to tensions when Turkey’s government is still reeling from last month’s failed coup, which it says Washington was too slow to condemn. US Vice President Joe Biden last week visited Turkey in an effort to smooth diplomatic strains.
Reports said that on Monday, Turkish-backed forces advanced on Manbij, a city about 320 miles south of Turkey’s border captured this month by the SDF, in which Kurdish fighters play a major part, with US help.
SDF-aligned militia said they were reinforcing Manbij but insisted none of the troops in the region or the extra fighters heading to the city were from the Syrian Kurdish YPG militia.
Turkey has said its warplanes and artillery have bombarded positions held by the Kurdish YPG militia in recent days. It accuses the YPG of seeking to take territory where there has not traditionally been a strong Kurdish ethnic contingent.
“The YPG is engaged in ethnic cleansing, they are placing who they want to in those places,” Turkish Foreign Minister Mevlut Cavusoglu told a news conference in Ankara, demanding Kurdish forces withdraw east of the Euphrates river, a natural boundary with areas of eastern Syria under Kurdish control.
