Air strikes in northern Syria have killed at least 23 people as government forces continue to attack areas held by opposition groups.
Officials said at least four people were killed after air strikes in western parts of Aleppo Province on November 13.
It was unclear who had carried out the air strikes in the area, where Syrian and Russian warplanes routinely make bombing raids.
The town of Atareb was also hit by air strikes, as was a border crossing in the Kurdish-held Afrin region in the northern part of the country, where several others were reported killed.
Meanwhile, rebel forces reportedly shelled a government-held district in the city of Aleppo. Government forces loyal to President Bashar al-Assad have reportedly recently recaptured areas in eastern Aleppo that were previously lost to rebel forces.
The government siege of eastern Aleppo, which is being aided by Russian forces, has left an estimated 275,000 people besieged and with no means of getting food, water, or medicine.
While air strikes on eastern Aleppo city have been reduced in recent days, attacks on rebel-held areas of western Aleppo Province have continued.
In the northern Idlib Province, the Britain-based Syrian Observatory for Human Rights and Aleppo Today media group said air strikes killed a mother and her four children on November 13.
The Syrian civil war began in 2011 and has killed at least 250,000 people while forcing millions of others to flee their homes.
