Syrian opposition activists are reporting that airstrikes on a rebel-held, eastern neighborhood in the city of Aleppo have killed at least 13 people, including children.

The Britain-based Syrian Observatory for Human Rights says the airstrikes hit the Marjeh neighborhood on Monday and that five children were among the casualties.

The Aleppo Media Center, an activist collective, also reported the airstrikes and gave the same death toll. It says 11 of the victims have the same family name of Qabs and ranged in age from a month-and-a-half-old baby girl and a 25-year-old man.

Rebel-held parts of Aleppo have been subjected to the worst aerial attacks since a cease-fire brokered by the U.S. and Russia collapsed in September. The air raids have killed hundreds, wounded many others and demolishing entire buildings.

A top aide of Syrian President Bashar Assad has visited Cairo to coordinate with Egypt in the fight against "terrorism" in the region.

Syria's state news agency reported on Monday that Maj. Gen. Ali Mamlouk, head of the National Security Bureau, led a delegation that visited Egypt the day before.

SANA says the Syrians met with top intelligence officials, including deputy chief of Egypt's intelligence agency. It says both sides agreed on "coordinating political standpoints" and strengthening the "cooperation in fighting terrorism."

Both countries are fighting extremists, including members of the Islamic State group. Egypt and Syria also have bad relations with Turkey's President Recep Tayyip Erdogan.

Egypt's pro-government Sada al-Balad and other news websites reported Sunday that six Syrians arrived on a private jet Sunday from Damascus.
