"The situation we are currently facing is one of legitimate defense. No-one can deny or limit Turkey's legitimate right to defense in the face of terrorist attacks," Erdogan said late Saturday.

The comments came after calls from Damascus and several other states across the globe on Turkey to end its shelling of Kurdish targets in Syria.

Damascus on Saturday denounced Turkish artillery shelling inside the Syria territory as an “outrageous violation” of international law, saying Ankara is targeting civilians in the Arab country.

On Friday, French President Francois Hollande warned that Ankara’s growing involvement in war-ravaged Syria was generating a risk of war between Turkey and Russia.

US President Barack Obama also had a telephone conversation with Erdogan on Friday, calling on the Turkish government to "show reciprocal restraint" by halting the shelling.

Russia has also expressed concern about Turkey’s shelling and military campaign inside Syria, describing it as “unacceptable.”

“The Kremlin is concerned by the growing tension on the Syrian-Turkish border,” Kremlin spokesman Dmitry Peskov told a teleconference with journalists in Moscow on Saturday.

Turkey has been bombing Syria’s northern territory since February 13 in order to stop the advances of Kurdish groups fighting Takfiri militants in the region. They fear Kurdish groups could create a stronghold near its southern border.

Ankara also blamed Syrian Kurdish fighters for a car bomb in the Turkish capital that killed 28 people earlier this week. However, a Turkey-based PKK splinter group, the Kurdistan Freedom Falcons (TAK), claimed responsibility for the attack.

The TAK was once linked to the Kurdistan Workers Party but it says its relationship with PKK militants has been severed. The PKK has been fighting for an autonomous Kurdish region inside Turkey since the 1980s, Press TV reported.
