COLOMBO, April 21 — The Sri Lankan government declared a curfew with immediate effect, junior defence minister Ruwan Wijewardene said today, following eight explosions that killed nearly 140 people, and mostly targeted churches and hotels.

"A curfew will be imposed until things settle down,” he told reporters in Colombo.

Government officials also said major social media networks and messaging apps, including Facebook and WhatsApp, have been blocked inside the country to prevent misinformation and rumours. — Reuters
