COLOMBO, Sri Lanka (AP) — The state-run tourism agency says the arrival of tourists in Sri Lanka rapidly declined in June, dealing a severe blow to the lucrative industry in the aftermath of the Easter Day suicide bombings that killed more than 250 people.

Sri Lanka Tourism Development Authority said Wednesday there were 63,072 tourist visits to Sri Lanka last month, a drop of 57% compared with June 2018, when the number was 146,828.

Seven suicide bombers struck three churches and three luxury hotels on April 21. Those killed included 45 foreigners mainly from China, India, the U.S. and U.K.

The Islamic State group claimed responsibility for the attacks.
