ISIS has said it smuggled a bomb on board a Russian airliner that crashed last month, after discovering a “way to compromise the security” at an Egyptian airport.

The latest edition of its official online magazine Dabiq said ISIS had initially planned to down a plane belonging to a country from the U.S.-led coalition targeting militants in Iraq and Syria.

The militants decided to instead target the Russian plane departing the Red Sea resort of Sharm el-Sheikh after Moscow began an air campaign in Syria in late September, the magazine said.

The photo showed a can of Schweppes Gold soft drink and what appeared to be a detonator and switch on a blue background.

It also published a photo of what it said were passports belonging to dead Russians “obtained by the mujahideen.”

It was not immediately possibly to verify the authenticity of the photos carried online in the magazine Dabiq.

ISIS also announced it had executed a Chinese and a Norwegian hostage, in its online English-language magazine.

Dabiq magazine printed photos of bodies it said were Chinese hostage Fan Jinghui and Norwegian Ole-Johan Grimsgaard-Oftsad.

A stamp-like caption overlaid on one of the photos read, “Executed after being “abandoned by the kafir (disbeliever) nations and organisations.”

Sisi, Putin discuss fight against terrorism

Meanwhile, the Egyptian presidency said on a statement on Wednesday that President Abdel Fattah al-Sisi and his Russian counterpart Vladimir Putin have discussed international cooperation in the fight against terrorism.

The two leaders agreed in a telephone call on the need for greater international security cooperation, according to the statement.

Russia’s FSB security service said on Tuesday it was certain a bomb had brought down a Russian passenger plane in Egypt’s Sinai on Oct. 31, joining Britain and the United States in reaching that conclusion.
