Twenty-four suspects have been arrested in Sri Lanka following the Easter Sunday bombings that killed 290 people and injured 500 more. Still no one has claimed responsibility for the attacks but Sri-Lankan officials say a little-known local jihadist group, National Thowheed Jamath is to blame. Sri Lankans in New Zealand are still in shock following the weekend terror attacks.
