Russian air strikes kill 60 civilians in Syria's Idlib

At least 60 people were killed in Russian air strikes overnight in the Syrian city of Idlib, the heaviest bombardment there since a cessation of hostilities was agreed in February.

The heavy air strikes carried out by Russian jets on a hospital and a mosque in Syria's opposition-held city of Idlib had also injured around 200 people.

The Observatory said the air strikes targeted a number of positions in the city, one of them next to a hospital. Seven children were among the dead, Observatory Director Rami Abdulrahman said.

The toll was likely to rise.

In an e-mailed statement, the Turkish foreign ministry called on the international community to act swiftly against what it called the "indefensible" crimes of the Russian and Syrian administration.
