Sri Lanka bomb blasts: Islamic State fighters carried out explosions that killed 321 and injured over 500, claim security sources

Two days after coordinated bombings at churches and hotels in Sri Lanka claimed at least 321 lives and left over 500 injured, security sources claimed that those who conducted the attack are Islamic State (IS) fighters.According to security sources, the terrorist group's Amaq news agency made the claim even though it did not give any evidence for it.The statement release by Amaq, according to security sources, read: "Those that carried out the attack that targeted members of the US-led coalition and Christians in Sri Lanka the day before yesterday are Islamic State group fighters."[caption id="attachment_6490711" align="alignleft" width="380"] Security personnel and investigators at St Sebastian's Church in Katuwapitiya, Negambo.
