NOBLES: Eastern Ghouta in Syria is still under heavy bombardment despite U.N. declassified -- declare is should say, ceasefire. Hospitals and clinics reportedly 520 people killed and 2500 injured since relentless air strikes and artillery began pounding the suburb eight days ago. CNN's Jomana Karadsheh is monitoring the situation, she joins us live from Amman, Jordan. Good morning.</s>JOMANAH KARADSHEH, CNN CORRESPONDENT: Good morning, Ryan. By all accounts Sunday was a day of escalation with activists reporting air strikes and artillery shelling pounding almost every part of eastern Ghouta. They reported the regime was trying to push into the area on several fronts in what they described as ground offensive. Overnight, we received disturbing reports coming from activists and medical groups, including the Syrian-American Medical Society about a suspected chlorine gas attack. SAMS says one of the hospitals it supports in eastern Ghouta received 16 patients. Including six children saying quote suffering symptoms indicative of exposure to chemical compounds. The health Director is reporting the same and saying the symptoms they showed were consistent to exposure toxic chlorine gas. We in CNN cannot verify this allegation, we have heard them in the past during this conflict and both sides have accused each other of using chlorine as a weapon. And it is always the case, it is the civilians who bear the brunt of this conflict, Ryan.</s>NOBLES: Absolutely heartbreaking, Jomana thank you for that report.</s>ROMANS: The Nigerian air force is stepping up its search for at least 110 school girls missing since the Boko Haram militant faction attack their school last Monday.
