‘Israeli earthquake bomb’ hits Syria in heaviest blitz on region for 12 years

THIS is the dramatic moment a colossal explosion erupted in Syria, marking the "heaviest strikes" to hit the region in over a decade - and even registering on the Richter scale.

Astounding video showed a giant mushroom-cloud fireball filling the sky alongside deafening sounds - with claims that the blast was caused by an Israeli strike.

The explosion is believed to have taken place in northwestern Syria, near the city of Tartus, according to the Syrian Observatory for Human Rights (SOHR).

Israel was targeting a munitions depot in the area, the war monitor claimed.
