BEIRUT, Dhu-AlHijjah 26, 1436, Oct 10, 2015, SPA -- Russian jets carried out air strikes on areas in western Syria on Saturday and a terrorist ISIS group stronghold in the north was rocked by a large explosion, Reuters cited the Syrian Observatory for Human Rights monitoring group as saying. Russia started bombing in Syria on Sept. 30 saying it was targeting the terrorist ISIS group militants, a campaign that has drawn Moscow deeper into Syria's more than four-year conflict. There was no immediate information on casualties. --SPA 14:01 LOCAL TIME 11:01 GMT www.spa.gov.sa/w
