The European Union is working on a new deal with Israel to deliver humanitarian aid to Gaza. EU foreign ministers are meeting Tuesday in Brussels to discuss the agreement, which aims to provide food and fuel to Gaza’s 2.

Ministers will also discuss Iran's nuclear program, tensions in Georgia and Moldova and new sanctions on Russia as the EU prepares its 18th sanctions package.

Since the EU deal was announced last Thursday, scores of people including children have been killed by Israeli forces while seeking aid from the Israel-backed Gaza Humanitarian Foundation. Kaag said that the EU must not fall into a trap of seeing aid as a bargaining chip, rather than a fundamental human right.

Opposition critics have denounced the proposal, with some likening the suggested site to a "concentration camp," which could lead to ethnic cleansing in the coastal enclave devastated by 21 months of conflict.

A planned “humanitarian city” inside Gaza intended to hold hundreds of thousands of Palestinians would be a “concentration camp,” former Israeli Prime Minister Ehud Olmert has warned.
