Bosnia was hit by a 5.4-magnitude earthquake today just hours after Albania was rocked by an even stronger quake which killed more than a dozen people.
Scientists said the quake had rattled Bosnia this morning with an epicentre around 50 miles south of the capital Sarajevo.
There were no immediate reports of injuries, but experts at a French-based seismology institute said there were 20million people living in the area where the quake was felt.
The Bosnia quake was too far away to be an aftershock of the 6.4-magnitude tremor in Albania, but may have been caused by it, said the European-Mediterranean Seismological Centre.
The earthquake in Albania earlier destroyed buildings and left people trapped under rubble in a tremor that was felt across south-eastern Europe - including in Bosnia.
The quake hit near the capital Tirana at 3.54am and brought severe damage to the coastal town of Durres and nearby city of Thumane.
One man in his fifties died after jumping from a collapsing building in Kurbin, while several bodies of a man and woman were removed from rubble in Thumane and a others were found in Durres. At least 14 are dead in total and hundreds of people have been treated for injuries.
