Watch: Overnight Israeli Strike In Syria So Large It Caused Earthquake

"This has begun in the overnight hours, with Israeli warplanes pummeling air defense systems and ammunition depots in Damascus and the coastal city of Tartous, near where a Russian naval base is located. The strike on Tartous resulted in the single biggest explosion seen in

Syria in years, unleashing a fireball and mushroom cloud so large it led to quick speculation it could have been a tactical nuke.
The London-based Syrian Observatory for Human Rights (SOHR) described that Israeli warplanes hit air defense units and "surface-to-surface missile depots" as part of a bid to degrade and disable Syria's military capability. SOHR also called it the "the heaviest strikes" on the region in over a decade.
The Telegraph wrote that "A 3.1 magnitude tremor was reported by the Geographic Survey of Israel’s seismology department at 11.49pm on Sunday night in the region of the bombings."
"The explosions in Tartous were extremely loud," Al Jazeera’s Resul Serdar, reporting from inside the country, additionally described. "Some experts are saying that might probably mean it was a chemical weapons production house." ZH
