Reuters reports: Fifty international aid groups and United Nations agencies issued a joint appeal on Thursday calling on Israel to lift its blockade of the Gaza Strip, which is ruled by Hamas Islamists.

“For over five years in Gaza, more than 1.6 million people have been under blockade in violation of international law. More than half of these people are children. We the undersigned say with one voice: ‘end the blockade now,'” the petition said.

Amongst the signatories were Amnesty International, Save the Children, the World Health Organization, Oxfam, the Office of the High Commissioner for Human Rights and five other U.N. bodies.
