The White House reported that US President Donald Trump called on Russia to end its support for the "atrocities" committed by the Syrian regime in the north of the country, expressing US concern about the violence in the Idlib region which is witnessing progress of the regime forces.
The White House said that Trump had telephoned his Turkish counterpart Recep Tayyip Erdogan, and thanked him for Turkey's efforts to prevent a humanitarian catastrophe.
Trump expressed Washington's desire to see the end of Russian support for what he described as the atrocities of the Bashar al-Assad regime, and to find a political solution to the Syrian conflict.
This phone call comes in conjunction with the progress of the regime forces in northern Syria, as it announced its control over the city of Aleppo in full, as part of its attack on the last opposition strongholds in the northwest of the country.
With the support of Russian aviation, the Syrian government forces have continued their offensive against Idlib and areas in the provinces of Aleppo and Lattakia since last December, killing more than 380 civilians, according to the Syrian Observatory, and the displacement of more than 800,000 people, according to the United Nations.
