At least 207 people were killed and hundreds more wounded in eight bomb blasts that rocked churches and luxury hotels in or near Sri Lanka's capital yesterday - on Easter Sunday. The attacks are the deadliest violence the South Asian island country has seen since a bloody civil war ended a decade ago.
There are 214 New Zealanders registered as being in Sri Lanka.
