Beirut- Regime air forces in Syria renewed aerial bombardment of rebel-held Aleppo eastern neighborhoods on Friday. All eyes have turned to the Turkish-led Operation Euphrates Shield making advances on al-Bab grounds, an ISIS controlled city in northern Syria.

Rupert Colville, spokesman for the U.N. High Commissioner for Human Rights, said the body was “gravely concerned” both for those “being squeezed into ever-shrinking areas” as regime forces advance, and for those who have fled. He also pointed out that over a 100,000 civilians have stayed inside rebel-held grounds in eastern Aleppo, and areas closed off by war.

Unfolding developments in Syria, especially the Turkish-led advance, have shaped a great challenge to be later faced by senior Russian and U.S. diplomats.

Euphrates Shield forces have stunned Syrian regime forces by resuming operations and attacks after a pause that surpassed 20 days, making a deafening advance of two kilometers.

The United Nations General Assembly voted 122 to 13 on Friday to demand an immediate cessation of hostilities in Syria, humanitarian aid access throughout the country and an end to all sieges, including in Aleppo. Among objecting states, were Russia, Iran and China, 36 other states abstained.

Thirty-six countries abstained in the vote on the Canadian-drafted resolution on the nearly six-year Syrian conflict. General Assembly resolutions are non-binding, but can carry political weight.

Hezbollah Secretary General Hassan Nasrallah on Friday delivered a “promised” victory being imminent for Syrian regime forces and their allies in the city of Aleppo. “There are great events taking place now in our region … (such as) what is happening in Aleppo, and the ramifications of the promised and coming victory for the whole battle in Syria and the region,” he said in a speech broadcast.
