Russian air strikes on multiple locations in the Syrian city of Idlib have resulted in about 23 deaths so far, with the death toll likely to rise as rescue workers scour through the attack sites.

The workers have been looking for survivors all through the night following the aerial attacks on Monday (30 May) evening. They have reportedly rescued some survivors, including a child, according to a Facebook post of the Civil Defence in Idlib.

The Syrian Observatory for Human Rights termed the air strikes as the heaviest bombardment since a ceasefire was agreed in February. The strikes targeted several locations in the stronghold of Syrian rebels as well as al-Qaeda affiliate Nusra Front. One of the targets was a location close to a hospital, Observatory Director Rami Abdulrahman was quoted by The New York Times as saying. He added that the casualties include seven children. He expected the death toll to rise further.

Russia is supporting Syrian President Bashar al-Assad to regain control of the country by fighting off the rebels who are seeking to end Assad's rule.
