Egypt’s President Abdel Fattah al-Sisi has backlashed at ISIS by linking it to the downing of a Russian passenger jet over Sinai Peninsula last year.

In a conference on Wednesday, Al-Sisi criticised the militant group for harming the tourism industry. He also said that the terrorists are doing all efforts to cause a gap between Egypt , Russia and Italy.  al-Sisi also indirectly pointed to the terrorist involvement in the crash.

“Has the confrontation and terrorism ended? No, not yet. Whoever downed that plane, what did he want?” el-Sisi said in a report by The New York times.

“Just to hit tourism? No. To hit relations. To hit relations with Russia.”

This was the first time that Egyptian President came across such case, says al-Ahram, a state-run news site.

CNN reported that, according to Al-Ahram, no report over terrorism and crash has been published by the investigators.  Russian investigators, on the other hand, revealed that the plane had a bomb, which was wired in a soda can.

An international chartered flight, Metrojet Flight 9268, was a Russian airline that took off from Sharm el-Sheikh International Airport, Egypt, en route to Pulkovo Airport, Saint Petersburg, Russia. While in flight, it exploded, killing 219 Russians, four Ukrainians, one Belarusian passengers and the crew on board.

Just after the crash, ISIS took to Twitter and claimed its involvement in the crash. The group shared a video with a statement by Abu Osama al-Masri (the leader of the ISIS branch in Sinai) claiming responsibility.  The group claimed in its online magazine called Dabiq, that the plane had a bomb.

In November 2015, Russian Federal Security Service announced a $50million reward to anyone with the information about the suspects that downed the plane. Officials revealed that the bomb was packed with 1 kilogram of explosives.

After the announcement of the reward, Russian military carried several airstrikes over Raqqa, Syria, the de facto capital of ISIS’ proclaimed caliphate.
