The US has decided to shut its embassy in Jerusalem from Wednesday through Friday due to the security situation in the region and to comply with Israeli guidance, the US State Department said on Tuesday.

"Given the security situation and in compliance with Israel Home Front Command guidance, the US Embassy in Jerusalem will be closed tomorrow (Wednesday, June 18) through Friday (June 20). This includes the Consular Sections in Jerusalem and Tel Aviv," the State Department said on X.

Meanwhile, the US military is deploying more fighter aircraft to the Middle East and extending the deployment of other warplanes, bolstering its military forces in the region as the war between Israel and Iran rages, according to three US officials.

One of the officials said the deployments include F-16, F-22 and F-35 fighter aircraft. Two of the officials stressed the defensive nature of the deployment of fighter aircraft, which have been used to shoot down drones and projectiles.

The Pentagon did not immediately respond to a request for comment.

Reuters was first to report on Monday the movement of a large number of tanker aircraft to Europe as well as the deployment of an aircraft carrier to the Middle East, providing options to President Donald Trump as Middle East tensions soar.

US Defence Secretary Pete Hegseth described the deployments as defensive in nature, as Washington looks to safeguard forces in the Middle East from potential blowback from Iran and Tehran-aligned forces in the region.

A fourth US defence official on Tuesday raised the possibility of the deployment to the Eastern Mediterranean of additional US Navy warships capable of shooting down ballistic missiles. The United States already has a sizeable force in the Middle East, with nearly 40,000 troops in the region, including air defence systems, fighter aircraft and warships that can detect and shoot down enemy missiles.

Israel launched its air war, its largest ever on Iran, on Friday after saying it concluded Iran was on the verge of developing a nuclear weapon. Iran denies seeking nuclear weapons and has pointed to its right to nuclear technology for peaceful purposes, including enrichment, as a party to the Nuclear Non-Proliferation Treaty.
