COLOMBO, Sri Lanka (AP) — Catholic services are being canceled for a second weekend in Sri Lanka's capital after the government warned of more possible attacks by the same Islamic State-linked group that carried out Easter suicide bombings.

Rev. Edmund Tillakaratne, spokesman for the Colombo diocese, said Thursday that Cardinal Malcolm Ranjith had canceled all Sunday services in the diocese based on the latest security reports.

Last week, Muslims were told to stay home for Friday prayers and all of Sri Lanka's Catholic churches were closed. Instead of the usual Sunday Mass, Ranjith delivered a homily before clergy and national leaders at his residence that aired on television.

The April 21 bombings at churches and luxury hotels killed 253 people and officials have warned that suspects linked to the bombings are still at large.
