The Islamic State, which has claimed responsibility for the downing of a Russian passenger plane over the Sinai Peninsula last month, released an image that purports to show the improvised explosive device used to kill all 224 people aboard the Metrojet flight from Sharm el Sheikh, Egypt.

In the latest issue of Dabiq, the Islamic State’s glossy online magazine, first disseminated through Telegram, an encrypted messaging app, a picture shows what ISIS says were the components of an IED: A Gold Schweppes Pineapple tonic water can and two devices containing wires, one with a switch.

It includes a caption that says, “EXCLUSIVE – Image of the IED used to bring down the Russian airliner.”

The veracity of the claim, and whether or not the specific device shown was used in the attack, could not immediately be determined. American and Russian officials have said that the debris from the Metrojet plane suggests that there was a bomb on board.

The accompanying article in the ISIS magazine says that Russia’s “arrogance” in bombing Syria prompted their operatives in the Sinai Peninsula to change their plan from blowing up a plane from one of the countries participating in the American-backed coalition against ISIS to attacking a Russian airliner.

“It was a rash decision of arrogance from Russia,” the article says. “And so after having discovered a way to compromise the security at the Sharm el Sheikh International Airport and resolving to bring down a plane belonging to a nation in the American-led Western coalition against the Islamic State, the target was changed to a Russian plane. A bomb was smuggled onto the airplane, leading to the deaths of 219 Russians and 5 other crusaders only a month after Russia’s thoughtless decision.”

As for the deadly attacks in France, the ISIS magazine says that the terrorist group had not forgotten that French airstrikes against Islamic State militants began on Sept. 19, 2014, in Iraq. And the article said that the leader of the Islamic State, Abu Bakr al-Baghdadi had vowed revenge.

“Thus the Islamic State dispatched its brave knights to wage war,” the article says. “The eight knights brought Paris down on its knees, after years of French conceit in the face of Islam.”

The issue did not provide any further details in how the Paris attacks were carried out.

The cover of the English-language magazine shows emergency workers in Paris, and the title “Just Terror.”

The image of a soda can used in what was purported to be an explosive device recalls the sort of “liquid bomb” three British men were planning to use in 2006 to blow up flights over the Atlantic. They were convicted in 2009 of planning to drain plastic soft-drink bottles with syringes and refill them with concentrated hydrogen peroxide, a bleaching agent also used as a propellant for rockets.

A test conducted for the BBC in 2008 by an explosives expert showed that a soft-drink bottle filled with liquid explosives could blast a hole in the fuselage of a passenger jet, leading to depressurization of the cabin at altitude.

But the device shown in the picture circulated by ISIS does not appear to be the same sort of bomb.

Alexander V. Bortnikov, the head of Russia’s Federal Security Service, said on Tuesday that traces of explosive material had been found in the wreckage of the Metrojet flight. Citing an unnamed security official close to the investigation, the Moscow daily Kommersant reported on Wednesday that Russian investigators theorized that the bomb might have been placed under a window seat near the back of the passenger cabin, not in the cargo hold.
