GAZA, Feb 2 (Reuters) - Israel was expected to reopen the border between Gaza and Egypt on Monday for people on foot, a move that would allow Palestinians to leave the enclave and let back in those who want to return after fleeing Israel's war in the enclave.

The reopening of the Rafah border crossing will be limited, with Israel demanding security checks for Palestinians entering and exiting. Israel and Egypt were expected to impose caps on the number of travellers.

Sick and wounded Gazans began crossing into Egypt to seek medical treatment on Monday after Israel permitted a limited reopening of the Palestinian territory's Rafah border post.

Around 150 people were due to leave the territory on Monday, and 50 to enter it, according to Egyptian officials, more than 20 months after Israeli forces fighting in Gaza closed the crossing.

JERUSALEM/CAIRO Feb 1 (Reuters) - Preparations to reopen Gaza's main border crossing in Rafah were underway on Sunday though it was uncertain any Palestinians would pass through it before the day's end, Israeli and Palestinian officials said.

Before the war, the Rafah border crossing with Egypt was the only direct exit point for most Palestinians in Gaza to reach the outside world as well as a key entry point for aid into the territory. It has been largely shut since May 2024.

US President Donald Trump on Sunday said he was hopeful of agreeing a deal with Iran after the country's supreme leader warned that any US attack on the Islamic republic would trigger a regional war.

Following the Iranian authorities' deadly response to anti-government protests that peaked last month, Trump has threatened military action and ordered the dispatch of an aircraft carrier group to the Middle East.

Iranian supreme leader Ayatollah Ali Khamenei on Sunday likened the recent protests to a "coup", warning that a US attack would trigger a broad conflict.
