Dozens of civilians and civilians were killed in government airstrikes in the Syrian province of Aleppo.
According to foreign news agency AFP, airstrikes by government forces killed 19 civilians.
Russia's ceasefire agreement was also sabotaged after the latest violent attacks.
Rami Abdul Rahman, head of the Syrian Observatory for Human Rights, said the attack happened around midnight last night.
According to him, the attack killed at least 26 anti-government fighters, most of whom were members of Hayat al-Sham.
The group also killed 29 government troops and allied militia personnel, the observer group said.
According to the Syrian state news agency 'Sana', a rocket was fired at a residential area in the government-controlled Aleppo city.
The rocket fired by the terrorist group killed 6 civilians and injured 15 others, the report said.
It should be noted that the UN has revealed that the number of attacks and killings on children on the war front around the world has increased threefold compared to 2010.
During the past 10 years, new war fronts have opened and children have suffered the most during these fronts, where thousands of children have been killed and millions of disabled and homeless in these horrific war fronts.
UNICEF cited three countries as the most vulnerable in ongoing conflicts around the world, warning that in 2019, Syria, Yemen and Afghanistan would be the most vulnerable.
It should be noted that Turkey has for many years been aware that the Kurdish militants in Syria have been involved in extremist activities in our country and have to prevent it from becoming any kind of threat.
Turkish President Rajab Tayyab Erdogan had allowed the army to launch an operation against Kurdish fighters a few months ago, saying it aimed to eliminate the 'terrorist path' in Turkey's southern border.
Many countries have expressed concern over the latest series of military action in Syria, saying it will increase the region's crisis, but Turkey said the aim of the operation is to make the region safer so that millions of refugees leave Syria. Can be sent back
