Croatian Prime Minister Zoran Milanovic said on Wednesday the government could not confirm "with 100 percent certainty" the death of a Croatian hostage purportedly beheaded by Sinai Province, the Egyptian offshoot of Islamic State.
He told reporters at a news conference that authorities have been trying to confirm the authenticity of a still photo being circulated on Twitter by social media accounts supportive of Sinai Province that showed a headless body.
