(CNN) -- The International Committee of the Red Cross called on Israel to allow it immediate access to Gaza, saying a trip into Gaza City revealed weak children laying with their dead mothers and other "shocking" scenes. Israeli artillery fires a shell toward Gaza from the Israel-Gaza border on Wednesday. Red Cross workers and four ambulances from the Palestine Red Crescent Society managed to enter the Zaytun neighborhood of Gaza City on Wednesday, according to a written release. The crew found four children, too weak to stand, next to their dead mothers in a house containing 12 corpses, the statement says.
