Prime Minister Jacinda Ardern has made a statement responding to the suggestion that the Sri Lanka bombings were retaliation for the Christchurch attacks. "We have seen reports of the statement from the Sri Lankan Minister of state for defence, alleging a link between the the Easter Sunday terrorist attack and the March 15 attack in Christchurch," she says. "We understand the Sri Lankan investigation into the attack is in its early stages. New Zealand has not yet seen any intelligence upon which such an assessment might be based." For further analysis, we talk to security consultant Paul Buchanan.
