According amateur videos posted on social networks, the violence in Syria have redoubled in intensity in recent days. The bombings were particularly important in Aleppo and Damascus. The al-Houla area in Homs was also targeted by a bombing by helicopter.
Street fighting continues in several cities such as Aleppo.
The shelling of a district in the east of Idlib has also left many injured.
But the saddest news of the day on Tuesday involves two schools, one in Idlib where seven children were killed in a bombing, the other in Douma, a suburb of the capital Damascus, where at least three children were killed.
Since the beginning of the civil war in March 2011, more than 200,000 people were killed in Syria.
