Syria has taken Turkey�s shelling of its territory to the UN, saying it amounts to �direct Turkish support for terrorist groups.�

In a letter on Sunday, the Syrian foreign ministry called on the UN Security Council to �put an end to the crimes of the Turkish regime.�

�The foreign ministry strongly condemns the repeated Turkish crimes and attacks against the Syrian people and Syria's territorial integrity,� Syrian official�news agency, SANA, reported.

Turkish forces continued to shell positions of Kurdish fighters of the Democratic Union Party (PYD) in the northern Syrian province of Aleppo for a second day on Sunday.

According to Turkey�s Anadolou news agency, the Turkish army attacked PYD targets around the town of Azaz by its howitzers stationed on the country�s border with Syria. Similar bombing took place on Saturday.

Ankara accuses the PYD, and its military wing, the Kurdish People�s Protection Units (YPG), of having links to the Kurdistan Workers� Party (PKK) militant group that has been fighting for an autonomous Kurdish region inside Turkey since the 1980s.

Turkish Prime Minister Ahmet Davutoglu said after the Saturday attacks that Ankara �will retaliate against every step (by the YPG).�

�The YPG will immediately withdraw from Azaz and the surrounding area and will not go close to it again.�

Davutoglu also noted that Turkey �can if necessary take the same measures in Syria as we took in Iraq and Qandil," referring to Turkey�s bombardment of PKK situations on Qandil mountain last year.

The Syrian government condemned Davutoglu comments as "blatant interference" in Syrian affairs.
