Fifteen Iranian servicemen were killed and several others seriously wounded in an explosion on Saturday at a military base near Tehran that happened as troops were moving munitions, a Revolutionary Guards spokesman told state TV.

My dear colleagues in the Revolutionary Guards were moving munitions in one of the arsenals at that base when, due to an incident, an explosion happened, Ramezan Sharif told news channel IRINN.

Some of the casualties are reported to be in a critical condition, he added.
