The military incidents occurred Monday in Ras al-Ain, the scene of heavy fighting and a refugee crossing point into Turkey, where rockets from a Russian-built MIG-25 fighter plane killed at least 20 people and demolished at least 15 buildings, and in the Golan Heights, seized from Syria by Israel in 1967, where sporadic Syrian mortar shelling led to a direct hit by Israeli tanks on Syrian artillery units, the newspaper reported.
