Blasts in Isfahan and north Tehran, Air raid sirens in Tel Aviv, north Israel

Air raid sirens sounded in the Tel Aviv area and parts of northern Israel on Tuesday, the military said, after warning of a fresh salvo of incoming missiles fired from Iran.

"A short while ago, sirens sounded in several areas across Israel following the identification of missiles launched from Iran toward the state of Israel," a statement from the military said, with residents of the Tel Aviv area and parts of the north urged to seek shelter.

Israel's military later lifted air raid warnings, saying it had intercepted "most" of a salvo of fresh missiles fired from Iran.

Iranian media meanwhile said several blasts were heard on Tuesday in the central city of Isfahan, which hosts multiple nuclear facilities, and in north Tehran, as Israel kept up its strikes for a fifth day.

"Several explosions were heard in the east and north of Isfahan and air defenses were activated against the hostile targets," the Mehr news agency reported.

Residents of Iran's capital were seen leaving the city and shops and the historic Grand Bazaar were closed Tuesday — the fifth day of the intensifying conflict started by Israel — hours after U.S. President Donald Trump urged the immediate evacuation of Tehran in an ominous social media post.

Iranian authorities insist everything is under control and no guidance has been issued, even as witnesses in Tehran say sirens blare every few hours and people rush for shelter amid ongoing Israeli attacks. On the roads out of Tehran to the west, traffic stood bumper to bumper, and long lines also could be seen at gas stations.

Trump left the Group of Seven summit in Canada a day early to deal with the conflict between Israel and Iran, telling reporters on Air Force One during the flight back to Washington: “I’m not looking at a ceasefire. We’re looking at better than a ceasefire.”
