Though the Sri Lankan government has suspected the local fundamentalist group National Towheeth Jamaath for carrying out the attacks but at the same time they say that it is a small outfit and can't carry out the blasts alone and some international groups may be involved in the attacks.
"The intelligence agencies have reported that there were international organisations behind these acts of local terrorists. Hence, it has been decided to seek international assistance for investigations," a government statement said.
