London: Islamic State of Iraq and Syria (ISIS) has published the photographs of two hostages, one Norwegian and the other Chinese, after executing them in the Syrian city of Raqqa as French, Russian and US airstrikes intensify post Paris massacre.

According to the Guardian, Norwegian Prime Minister Erna Solberg said that they had no reason to doubt that ISIS had murdered one of its citizens held hostage in Syria.

Images of the dead Norwegian, identified as Ole Johan Grimsgaard-Ofstad, 48, were published in the latest issue of the ISIS magazine Dabiq along with the pictures of murdered Chinese hostage.

Solberg said that the government did not pay any ransoms because they should not let the terrorists win even if it hurts.

Raqqa has been under heavy bombardment over the last three days after a storm of attacks in Paris by ISIS that provoked intensified airstrikes by France along with raids by the US-led coalition and Russia that have killed close to three dozen militants.
