Turkey's Çavuşoğlu urges Russia to halt regime attacks on rebel-held Idlib

Turkey's foreign minister urged Russia on Wednesday to halt the regime attacks in the war-torn Arab country, a day after airstrikes on rebel-held sectors and the shelling of government-held areas killed at least 18 people, including an entire family.

In his remarks, Foreign Minister Mevlüt Çavuşoğlu insisted it was Moscow's responsibility to stop the violence as Russia has been a staunch supporter of the Assad regime in the civil war.

The pro-Assad forces have been carrying out an offensive on the northwestern province of Idlib, the last rebel stronghold in the country, and the rebel-held parts of nearby Aleppo province. The fighting has displaced hundreds of thousands of people, many of whom fled to areas closer to the border with Turkey.

Dozens of fighters have been killed on both sides in recent days as clashes intensified. The fighting comes despite a new cessation of hostilities agreement between Russia and Turkey that went into effect earlier this month. Moscow and Ankara stand on opposing sides of the conflict in Syria.

"Russia is the guarantor of the (Assad) regime," Çavuşoğlu told a panel at the World Economic Forum, in Davos, Switzerland. "Russia is obliged to stop this aggression."

"The situation in Idlib is our main focus because the regime has been increasing its aggression," he added. "Already, 400,000 people have been displaced and moved toward our border."

The province of Idlib is dominated by al-Qaida-linked militants but is also home to 3 million civilians. The United Nations has warned of the growing risk of a humanitarian catastrophe along the Turkish border.
