An air strike by Israel on Syria caused an explosion so big it could be felt more than 500 miles away.
Video footage shows a enormous orange blast in the distance that fills the sky, shortly before the explosion can be heard.
The attack of what Israel says are military sites in Syria’s coastal Tartus region has been described as the ‘heaviest strikes’ since the country began targeting the area over a decade ago.
The explosion was so large, it reportedly measured as a magnitude 3.0 on seismic sensors.
One researcher, Richard Cordaro, said the blast was detected by a magnetometer station 820km (509 miles) away in Isnik in western Turkey, MailOnline reports.
Tartus has been the site of one of Russia’s two military bases in Syria and was used as an ammunition depot and a naval base.
It’s thought the ammunitions may have contributed to the size of the blast, as well as secondary explosions.
Syrian Observatory for Human Rights said today: ‘Israeli warplanes launched strikes’ targeting a series of sites including air defence units and ‘surface-to-surface missile depots’.

It added that the attack were ‘the heaviest strikes in Syria’s coastal region since the start of strikes in 2012’.
The pounding comes just a week after the fall of the country’s dictator Bashar al-Assad, who had Russia’s support.
Although Israel has not commented on today’s attack, prime minister Benjamin Netanyahu said last week he approved the bombing of strategic military sites left by the Syrian military ‘so that they will not fall into the hands of the jihadists’.
Meanwhile, Giora Eiland, the former head of Israel’s National Security Council, told The Telegraph that one of the nation’s main strategic priorities was to make sure the next leader of Syria would not have the ability to attack Israel.
He said: ‘There is no army to stop us. So it’s a very easy mission to destroy Syria’s strategic capabilities.’
The military site hit today was used for the delivery of armaments and supplies as Russia intervened in the Syrian civil war in 2015.
Vladimir Putin expanded the facility in 2017, after Assad offered Russia a free 49-year lease on the site in exchange for helping keep him in power.
Experts believe the number of Russians stationed there fell significantly after Putin invaded Ukraine.

Russia’s foreign ministry said it had evacuated some of its diplomatic staff from Syria since Assad’s fall.
