A methane leak caused a coal mine blast in Tabas, Iran, state media said. An emergency official said the toll is likely to rise as rescuers struggle to reach victims.

An explosion in a coal mine in eastern Iran killed at least 34 workers and injured 17 others, officials said Sunday, marking one of the worst mining disasters in the country’s history as others remained missing hours after the blast.

The two people killed in a north-central Idaho gas station explosion last week have been identified; two others remain hospitalized. The incident, which occurred on Wednesday afternoon, left two dead and four injured.
