According to reports, three people were killed when the militants shelled Aleppo’s Seif al-Dawla neighborhood late on Wednesday night.
Aleppo has been divided between the government forces and militants since 2012, a year after the conflict broke out in the Arab country.
Earlier in the day, the General Command of the Syrian Army announced in a statement that the truce will come into force as of 1 p.m. local time (1000 GMT) on Wednesday and will be in effect until July 8 midnight.
Before the 72-hour truce was announced, at least three civilians were killed when Takfiri militants attacked Eid al-Fitr prayers at a residential neighborhood in the embattled province.
Eid al-Fitr marks the new lunar month of Shawwal and the end of Ramadan — the ninth month on the Islamic calendar — when Muslims refrain from eating, drinking, smoking, and indulging in anything that is in excess or ill-natured from dawn to dusk.
Syria has been gripped by foreign-backed militancy since March 2011. UN Special Envoy for Syria Staffan de Mistura estimates that over 400,000 people have been killed in the conflict. The UN has stopped its official casualty count in Syria, citing its inability to verify the figures it receives from various sources, Press TV reported.
