CAIRO, March 23 (Reuters) - Islamic State released on Saturday a photo of what it said were the four attackers behind a shooting rampage that killed at least 143 people in a concert hall near Moscow on Friday, the militant group’s Amaq news agency said on Telegram.

“The attack comes within the context of a raging war between the Islamic State and countries fighting Islam,” Amaq added in a statement citing security sources.

Islamic State claimed responsibility for the attack but there were indications that Russia was pursuing a Ukrainian link, despite emphatic denials from Ukrainian officials that Kyiv had anything to do with it.
