GAZA, Feb. 28 (Xinhua) -- Israeli authorities announced on Saturday evening the closure of all crossings into the Gaza Strip, including the Rafah land crossing, until further notice amid heightened tensions with Iran.

In a statement, Israel's Coordinator of Government Activities in the Territories (COGAT) said: "Following recent developments, security measures have been taken to safeguard lives." It added that crossings in the Gaza Strip, including Rafah, would remain closed until further notice.

The statement said West Bank crossings would also be closed, except for essential workers holding designated permits, who will be allowed to use the Eyal, Tarqumiyah, and Qalandia crossings.

COGAT stressed that Israel would maintain a policy of "zero tolerance toward any attempt to undermine security stability" and would take strict measures against anyone involved in what it described as terrorist activities. It also warned that any incitement or support for Iran would trigger a severe response.

Earlier Saturday, Israeli authorities announced a series of precautionary measures amid escalating regional tensions.
