(CNN) — Syrian warplanes pounded volatile northern regions of the nation Tuesday, activists said.
Planes struck Maaret al-Numan and neighboring villages in Idlib province in the north, the opposition Local Coordination Committees of Syria said.
The town is strategically important to the government. It’s on a main highway connecting Damascus and Aleppo, and the government needs it for moving reinforcements.
The LCC said at least 20 people died during “aerial shelling” in al-Mayadeen in Deir Ezzor province. They are among the 83 people slain across the country Tuesday, the group said.
Aerial shelling was reported in the Damascus suburb of Abada, and several people were wounded, the LCC said. It also occurred in the Raqqa province town of Ali Bajiliya amid clashes between rebels and government forces.
One person was killed and others were wounded in Hama by a bomb planted by regime forces, the LCC said.
More than 30,000 people have been killed in the country’s 19-month-long conflict, regarded as a civil war.
Syrian state media said the nation’s armed forces in Aleppo killed “terrorists” and destroyed vehicles, including one equipped with a missile launcher. It also said it killed “terrorists” in the Damascus countryside and other provinces.
