Polish hikers killed by lightning in Pieniny mountains
Four people hiking in mountains in southern Poland were killed by lightning, Polish media report.
The four, a couple in their 50s, their daughter and her boyfriend were last seen on Wednesday when they went off the trail in search of shelter from a violent storm.
Their bodies were found on Friday at the bottom of a ravine in the Pieniny mountains, near the Slovak border.
The Polish authorities will investigate the exact cause of death.
"It is extremely rare for a single bolt of lightning to kill four people," mountain rescue official Mariusz Zarod told the Reuters news agency.
