Three children were killed and 10 injured in a militants' shelling of a school in Syria's Aleppo, the Russian General Staff said.

Terrorists ramp up the shelling of western Aleppo in Syria, with a school and a humanitarian corridor their latest targets, Russian Defense Ministry spokesman Maj. Gen. Igor Konashenkov said Thursday.

"This afternoon during classes at a school in the Hadaiq al Andalus region, a mine and a gas cylinder hit the school classrooms from terrorist-controlled eastern Aleppo," Konashenkov stated.

A nearby humanitarian corridor in Masharqa district was also targeted, resulting in 12 civilian deaths and more than 20 injuries, Konashenkov stated. "Why does the UNICEF and certain permanent UN Security Council members stubbornly refuse to notice any of this?"

Russian Defense Ministry repeated that Russian and Syrian air forces refrain from flights in 10km (6.2 mile radius) vicinity of Aleppo for the 10th day running. "For the 10th day, the Russian Aerospace Forces and the Syrian Air Force have not made any flights near the 10-kilometer zone around Aleppo," spokesman Maj. Gen. Igor Konashenkov said.

Another two schools came under attack in Syria on Thursday after an Idlib school had been bombed, United Nations International Children's Emergency Fund (UNICEF) Executive Director Anthony Lake announced in a release.

UNICEF noted that the latest attacks bring the number of attacked schools since October 11 to five. "Yesterday, when a school compound in Syria was repeatedly attacked, killing dozens of children and teachers, we thought we had seen the depths of depravity," Lake said on Thursday. "Today's reports of attacks on schools in Douma and western Aleppo should deepen our disgust and outrage."

On Wednesday, UNICEF announced that at least 22 children and six teachers were killed in an attack on a school compound in the Syrian city of Idlib.

Lake said attacking schools and killing children is simply inhuman. "If the perpetrators cannot find their own sense of humanity, they should heed the condemnation of the world," Lake added.
