Videos released on the internet on Tuesday (May 9) purport to show Syrian regime missiles being parachuted on the rebel-held Syrian town of al-Latamneh and clouds of smoke rising above Kafr Zita in the northern part of Hama province.
The Syrian Observatory for Human Rights, a Britain-based war monitor, reported that more than 30 shells had been dropped on Tuesday morning on areas in the towns of Latamneh and Kafr Zita.
Latamneh was also hit by airstrikes on Monday (May 8).
Fighting between Syrian rebel and government forces eased on Saturday (May 6) as a Russian-led effort to shore up a ceasefire took effect, although battles continued on important frontlines near Hama and Damascus, rebels and the war monitor said.
The agreement said four de-escalation zones would be established in Syria for a period of six months which could be extended if the three signatory countries, Iran, Turkey and Russia, agreed. Weaponry and air strikes were not to be used in those zones by combatants, the text said.
The agreement also included creating conditions for humanitarian access, medical assistance and the return of displaced civilians to their homes.
