Prime Minister Benjamin Netanyahu warned Friday that Israel would impose a very heavy price on any power behind the FlyDubai incident, according to France 24.

The aircraft carrying 174 people was forced to make an emergency landing in Saudi Arabia after the co-pilot apparently stabbed the pilot, according to France 24. US President Donald Trump said he was hearing that Iran was involved and that the country will be hit very hard if so, without presenting evidence, according to France 24. Netanyahu admitted Thursday that there was a loophole in vetting pilots from countries without diplomatic relations with Israel, according to the Hindustan Times.
