Sri Lankan police have found 87 bomb detonators at the main bus station in Sri Lanka.
Officers made the discovery in the capital, Colombo, on Monday, a spokesman said, a day after suicide bombers attacked churches and hotels killing 290 people and wounding about 500.
Security forces are carrying out searches across the island to find those behind the bombs.
No group has claimed responsibility, however a Sri Lankan government official has said a local militant group named National Thowfeek Jamaath is responsible.
Health Minister Rajitha Senaratne told a news conference on Monday that all seven bombers linked to the near-simultaneous attacks on three churches and three luxury hotels in and around Colombo were Sri Lankan citizens.
