The Syrian Observatory for Human Rights says at least 20 people have died in airstrikes in the northwest province of Idlib, including the spokesperson for the militant group al-Nusra. It is not clear who launched the airstrikes—the Syrian Observatory said the strikes were launched by Assad’s regime or the Russian military, while other groups said it was a U.S. drone strike. This comes as the partial ceasefire in Syria appears to be under threat amid heavy fighting in the north and accusations from France that Assad’s regime has violated the ceasefire by continuing to launch airstrikes against civilians on the outskirts of Damascus.
