US Secretary of State John Kerry and his Russian counterpart, Sergei Lavrov, have agreed provisionally on cessation of hostilities in Syria, the former confirmed on Sunday. However, multiple blasts in Homs and parts of Damascus, the capital of Syria, have created concerns over whether the agreement would actually come into force.

“We have reached a provisional agreement in principle on the terms of a cessation of hostilities that could begin in the coming days,” Kerry told a news conference in Amman, as quoted by Reuters. “The modalities for a cessation of hostilities are now being completed. In fact, we are closer to a ceasefire today than we have been.” The conference was jointly held by with Jordanian Foreign Minister Nasser Judeh.

According to the UK-based Syrian Observatory for Human Rights, Homs, a western Syrian city was rocked by twin car bomb blasts on Sunday that killed at least 59 people and injured 100 others. A number of blasts occurred in parts of Damascus as well by suicide bombers, taking the lives of at least 87 more and injuring further 180. The ISIS has claimed responsibility for the attacks.

The airstrikes carried on by Russia since September aimed the rebels fighting the Bashar al Assad regime for the past five years. It led to further destruction of Syria, which was already ravaged by the longstanding civil war that killed more than a quarter of a million of its people.

On Saturday, Syrian President Assad said that he is ready for a ceasefire provided that the ceasefire in fighting is not used by the “terrorists” to their advantage and that the countries backing the insurgents also stop, the NBC News reported.

We have said that we are ready to stop military operations, but the issue relates to more important factors, such as preventing terrorists from using it to improve their positions,” Assad said in an interview with Spanish newspaper El Pais.

He added that, other countries, especially Turkey, should stop sending more terrorists or any for form of logistical support.
