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.

The Israeli military has opposed Prime Minister Benjamin Netanyahu’s ‘humanitarian city’ in the Gaza Strip, which has been widely condemned as a concentration camp for Palestinians. The military has warned that the plan is not workable and will likely compromise ongoing ceasefire talks with Hamas.

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.

Egypt's foreign minister said on Monday that the flow of aid into Gaza has not increased despite an agreement last week between Israel and the European Union that should have had that result.

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.
