The demonstrators called to overthrow the Assad regime and expressed their sympathy and support to the forcibly displaced persons from Maarat al-Nuaman city.
They asked International community to press Assad regime and Russia to stop killing civilians and to release the detainees.
On Monday, Assad warplanes and helicopters intensified bombardment on Idlib, killing 21 civilians, including three children and injuring 82 others, including 19 children, violating a ceasefire announced by Russia and Turkish Defense Ministry on the 9th and 12th of January.
Last month, thousands of Syrian demonstrators and activists worldwide took to the streets in more than 50 cities and capitals worldwide chanting anti-Russia and Assad militia slogans and condemning Putin and Assad crimes in Syria.
Assad-Russian warplanes have committed dozens of massacres in Idlib and Hama countryside since they launched their bombing campaign on the 30th of April, largely violating the de-escalation zone deal reached between Russia and Turkey.
