Gaza, Ramadan 14, 1435, Jul 11, 2014, SPA -- Israeli occupation's air offensive in the Gaza Strip has claimed 103 Palestinian lives so far, nearly half of them women and children, medics said Friday as Israel moved three infantry brigades closer to the coastal enclave in preparation for a possible ground offensive. The buildup near the border with Gaza is to be strengthened by one or two further brigades in the coming days, , dpa cited Israel military spokesman Peter Lerner as saying The preparations were being carried out as the United Nations questioned whether Israel's repeated airstrikes are legal, given the high number of civilian casualties. -- SPA 20:59 LOCAL TIME 17:59 GMT www.spa.gov.sa/w
