Air raids on rebel-held towns across Syria killed 26 people on Monday, activists said, two days after the U.N. Security Council passed a resolution demanding an end to indiscriminate shelling and aerial attacks.

Syria’s almost three-year-old conflict has raged on despite peace talks that began in Geneva last month and the passage of the U.N. resolution, a rare moment of unity between the West and Russia, President Bashar al-Assad’s strongest backer.

Two women and 10 children were among the dead in government air raids on the town of al-Neshabieh, in the eastern outskirts of Damascus, near a railway marking the frontline between Islamist fighters and Assad’s forces backed by Lebanese Hezbollah militants, and in the province of Homs to the north.
