Islamic State supporters are celebrating the Sri Lanka suicide terror campaign which killed 290 people on Easter Sunday and left around another 500 injured.
The SITE Intelligence Group, which tracks extremist activity online, said ISIS radicals were flattering the terror attacks as revenge for the Christchurch mosques shooting.
No group has officially claimed charge for the blasts at five-star hotels and churches but Sri Lankan police say a previously unknown Muslim extremist group were the subject of an intelligence warning ten days before.
Early evidence points towards Islamist group National Thowheed Jamaath (NTJ), according to intelligence chiefs, who warn that more attacks are likely.
Rita Katz, director of respected terror observing SITE Intelligence Group, said IS supporters have commended the attacks on social media, ‘celebrating casualties’.
She claimed that the online praise indicated the group may be preparing to take charge for the attacks.
