Five people have been killed in two separate explosions in Iran which local officials and state media say were caused by gas leaks, BBC reported. 

One person was killed and 14 injured in a blast at a residential building in the southern city of Bandar Abbas on the Gulf coast, a local official told Iran's semi-official Mehr news agency.

Another explosion killed four people in the south-western city of Ahvaz, the state-run Tehran Times reported, according BBC.
