Several local NGOs in Gaza say Hamas has prevented aid groups from distributing emergency assistance after they refused to comply with Hamas regulations. "We received information that supplies brought in from abroad were being sold on the market," deputy minister of social affairs Sobhi Redwan told IRIN, saying UNRWA (the UN agency for Palestinian refugees) was bringing in supplies for non-UN institutions and donors. International aid agencies like Oxfam and CARE say the "logistics cluster" coordinated by the World Food Programme (WFP) is the only mechanism under which trucks are sent into Gaza.
