TEHRAN, Iran (AP) — Iran said Tuesday it believes the remaining workers trapped by an explosion at a coal mine in the country's east have died, bringing the death toll in the disaster to at least 49.

A provincial emergency official, Mohammad Ali Akhoundi, gave the death toll in a report carried by Iranian state television from the mine in Tabas.

Figures for the numbers of miners inside the mine at the time have fluctuated since the methane gas leak Saturday sparked an explosion.
