TEHRAN, Iran (AP) -- Iran's semi-official Fars news agency is reporting that an explosion in a subway tunnel in the capital, Tehran, has killed two workers and damaged a gas pipeline.
The report said that the explosion took place at 4:30 a.m. Friday while digging took place on a subway tunnel in northwestern Tehran.
The official IRNA news agency also reported that the explosion damaged phone cables, water and gas pipelines but it did not report any casualties.
In March, a heating gas capsule exploded injuring at least 12 people in a bazaar in the capital. Such explosions are occasionally reported in Iran, mainly because of poor safety measures.
