The incident on Friday evening occurred two days after a gunman shot dead two Bosnian soldiers and wounded another in an attack on a betting shop and city bus on the outskirts of the capital Sarajevo, before committing suicide.

 

The blast in the tunnel occurred near the village of Salakovac 20 km (12 miles) north of the southern town of Mostar, a Defense Ministry statement said.

 

Authorities had no immediate information on who may have been responsible for the blast or their motive. They also could not confirm if the device was a bomb.
