The head of Doctors Without Borders said Monday that Israel’s decision to end the group’s humanitarian operations in Gaza would have catastrophic consequences for Palestinians.

Israel announced on Sunday that it was terminating all the activities in Gaza and the West Bank by the organization, known by its French acronym MSF, after it failed to provide a list of its Palestinian staff.

MSF slammed the move, which takes effect on March 1, as a "pretext" to obstruct aid.

"This is a decision that was made by the Israeli government to restrict humanitarian assistance into Gaza and the West Bank at the most critical time for Palestinians," MSF secretary-general Christopher Lockyear warned in an interview with AFP at the charity's Geneva headquarters.

"We are at a moment where Palestinian people need more humanitarian assistance, not less," he said. "Ceasing MSF activities is going to be catastrophic for the people of the Gaza Strip and the West Bank".
