Bosnia coal miners trapped underground after earthquake

Thirty-four miners remain trapped in a central Bosnian coal mine which collapsed in a gas explosion following an earthquake, officials say.

Twenty-two other miners escaped before the pit collapsed on Thursday.
Rescuers are trying to reach the trapped miners, who are believed to be more than 500 metres (1,600 feet) below ground, mine officials said.
The 3.5-magnitude quake struck 53 km (33 miles) northwest of the capital Sarajevo, Bosnian TV reported.
"The rescuers are deploying superhuman efforts to save their comrades. They confirmed they are all together and doing well," said Nermin Niksic, the prime minister of the country's mainly Muslim-Croat entity, the Federation of Bosnia and Hercegovina.
It is the third accident involving gas explosions at the Zenica coal mine since the start of the year.
