Nearly 60 lawmakers in the United Kingdom have written to Foreign Secretary David Lammy this week, calling out Israel’s plans for the “ethnic cleansing” of Gaza and demanding the country immediately recognise Palestine as a state, Al Jazeera reports.

The 59 lawmakers, all from the governing Labour Party, criticised Israeli Defence Minister Israel Katz’s plans to force Gaza’s 2.1 million Palestinians into a so-called “humanitarian city” — likened by some analysts to a concentration camp — built on the ruins of Rafah.

The letter, sent to Lammy on Thursday and made public on Saturday, cited Israeli human rights lawyer Michael Sfard as saying Palestinians were being pushed to the southern tip of Gaza “in preparation for deportation outside the strip”, slamming the move as “ethnic cleansing”.

They urged the foreign secretary to stop Israel’s “operational plan for crimes against humanity”. It also called on London to follow the lead of French President Emmanuel Macron, who recently announced an intent to recognise a Palestinian state, so as not to undermine its own policy in support of a two-state solution.
