Four civilians, including a school student, were gunned down Sunday by armed "terrorist" groups in the central province of Hama, state-run SANA news agency reported.
Three others were seriously wounded in that attack, said SANA, adding that the armed group ambushed the civilian bus between the Kafr al-Toun and Tal Skein villages in the suburbs of Hama, Xinhua reported.
Earlier in the day, unidentified gunmen shot dead a judge and the general attorney of the northwestern province of Idlib in Syria, according to SANA.
The armed group targeted the officials' car in which they were heading to work, killing Idlib's General Attorney Nidal Ghasal and Judge Mohammad Ziadeh along with their driver.
The Syrian government has blamed the unrest in Syria on plots by terrorists and foreign-backed armed gangs and said more than 2, 000 army and security personnel were killed during the past months, while the UN put the death toll in the Syrian unrest at around 6, 000.
