The ceasefire agreement in Syria reached by the United States and Russia has officially come into effect on September 12, and ceasefires have begun to be implemented in most areas of the country.

Within hours of the agreement taking effect, explosions were heard along supply lines in rebel-held areas of the eastern city of Aleppo and the southern city of Daraa. In addition, attacks also occurred in Homs and Deir ez-Zor that day.

In fact, due to repeated failures in previous negotiations, the ceasefire agreement negotiations last weekend were also not optimistic. However, after 13 hours of intense negotiations, a preliminary agreement was finally reached. The United States and Russia also plan to establish joint air operations after the ceasefire agreement is implemented to jointly combat extremist organizations such as the "Islamic State" (ISIS).

According to the final decision, the ceasefire will begin at 19:00 on the 12th local time in Syria (00:00 on the 13th, Beijing time). Regarding the reported continuation of the conflict, US Secretary of State John Kerry admitted in Washington on Monday that although violence and sporadic conflicts are decreasing, it is too early to conclude that the ceasefire has been successful.

“There is no doubt that you will still hear sporadic violence. This is also the natural process of the ceasefire agreement. There will be more challenges in the coming days, but this is at least an opportunity to solve it. ” Kerry said.

Kerry also hinted in his speech that the Assad regime would launch an air strike against the "Conquest Front" (now officially renamed Jabhat Fateh al-Sham) once it obtains approval from Russia and the United States. But White House spokesman Colby later denied it. He said, "The biggest purpose of this agreement is to prevent the Syrian government air force from using force against opposition chassis." ”

Kerry also expressed appreciation for the courage of the opposition parties to stay away from the "Conquering Front". Although the "Front of Conquest" has officially announced its separation from Al Qaeda, the United States still regards it as part of Al Qaeda and is listed as a terrorist organization.

Some analysts pointed out that it is currently difficult to maintain a ceasefire for seven days. For example, although the main opposition group in Syria, the "Syrian National Coalition", has finally confirmed that it will implement the ceasefire agreement, there are still some opposition parties that are still unclear about whether to join the agreement.

“We want to know what guarantees we can get,” Salem al-Muslet, spokesman for the High Negotiations Committee, the main opposition group in Syria, said, “What is the definition of ‘terrorism’? ”

There are still differences within the opposition. Which areas controlled by the opposition are still considered valid targets is a core issue of concern to all opposition parties, especially in the two provinces of Aleppo and Idlib. Over the past five years, global jihadists and Islamic extremists have emerged in large numbers in these two provinces.

Since we have just entered the implementation period of the agreement, there are still some opponents who are not sure whether to join the agreement, so the further implementation of the agreement remains to be seen.

Earlier, Turkey also expressed cautious support for the ceasefire, and Iran and Hezbollah, which are involved in the situation in Syria, also expressed similar positions.

For nearly a year, Russia has supported the Assad regime by bombing opposition groups and emerged as a key driver of the ceasefire agreement. Russia has also promised to open rescue routes to Aleppo and other places if the opposition completely breaks away from the mujahideen.

Ahead of Monday's ceasefire, Syrian President Bashar al-Assad said his government was determined to take back every inch of land occupied by terrorists and rebuild the country. He also called for reconciliation among all Syrian people in public speeches.

According to the ceasefire agreement, if the ceasefire can successfully last for seven days, the United States and Russia will establish a joint operations center to share intelligence and coordinate air strikes against terrorist targets.
