The video shows Ukrainian attack on Russian ships in Crimean port of Sevastopol on 23 March.

Israeli war jets attacked an Iranian consulate building in Damascus, Syria, on Tuesday (April 2), killing at least 13 people, including General Mohammad Reza Zahedi, who was a senior leader of the Iranian Quds Force. Iran has vowed revenge against Israel also. Against this backdrop, a video of a huge explosion in a city at night time has been shared on social media with claims like “Iran started attack Tel Aviv with heavy missiles. Tel Aviv is now under heavy bombardment, and fires are burning”.

Fact Check-

Our investigation began with a reverse image search of key frames from the viral video, which led us to an extended version of the same video uploaded to the official YouTube channel of The Telegraph on 24 March. The caption states, “Huge explosions rock Sevastopol after Ukrainian missile attack”.

The description mentions that Ukrainian military claims to have hit two Russian warships and other facilities in the Black Sea, including a communications center and infrastructure facilities belonging to the Russian Black Sea Fleet. The extent of the damage is unknown, but a Russian official reported a major Ukrainian air attack and over 10 missiles being shot down over Sevastopol.

Upon further search, we found more reports of this incident. It states, Ukraine reported the destruction of two of Russia's large landing ships, followed by a damaging strike on the Ivan Khurs, an intelligence-collecting ship. The report quotes an Ukranean reporter like this “Ukrainian missiles struck the 744th Communications Center of the Black Sea Fleet in Russian-occupied Sevastopol, Crimea, which is the communication and coordination nerve center of Russian air, navy, and air Défense assets in the Black Sea".

As a result, we may conclude that the video from Crimea's Sevastopol was falsely shared as showing Iran's missile attack on Israel.
