Guterres: 'I'm deeply alarmed by the renewed escalation in the Middle East.All attacks must stop immediately.The ceasefires in Lebanon, Iran & Gaza must be fully respected.Any steps that could undermine ongoing diplomatic efforts must be avoided.I'm also deeply concerned by Israel's decision to close crossings into Gaza & reiterate my call for the immediate reopening of all crossings to ensure the rapid, safe & unhindered passage of humanitarian assistance at scale throughout Gaza.'
