DAMASCUS, March 23 (Xinhua) -- At least 15 people were killed on Sunday across Syria in multiple mortar attacks by armed militant groups, local media reported.
Eight people were killed when mortar shells landed near the Sheikh Daher Square and the entrance of the Hanano marketplace in Syria's northern coastal province of Latakia.
Another two people were killed, including a schoolgirl, by mortar shelling on the Kabbas district of the capital Damascus and the vicinity of the Ministry of High Education in the Jamarek area.
In the central province of Homs, four people were killed by mortar attacks against the districts of Hamra, Insha'at, al-Khudur and the Karm al-Shami.
A man was also killed by a mortar attack against the city of Busra in the southern province of Daraa.
The Syrian rebels have intensified their mortar attacks following their defeat in battles against the Syrian troops in central and southern Syria.
Moreover, the militant groups have launched a wide-scale offensive in the border town of Kasab in Latakia to strip the government troops of the Kasab border crossing with Turkey and to cover for their losses in the south.
More than 100,000 people have been killed and millions displaced since rebels started to fight against the Syrian government in March 2011.
