Czech police are investigating a fire that killed 11 people, including three children.
Saturday’s fire at a building in the northeastern town of Bohumin has been described as the worst fire in the country’s history.
Six people died in the blaze and five more were killed after jumping from an 11th-floor balcony in an attempt to escape the flames.
Ten people, including two firefighters and a police officer, were injured.
Bohumin is located on the Czech-Polish border, about 300 km east of the capital, Prague.
Governor of the Moravian-Silesian region Ivo Vondrak said the fire appeared to have been started on purpose.
According to eyewitness reports, a man was handcuffed at the scene after calmly admitting to police that he started the fire.
Police declined to comment on the allegations, but confirmed that one person had been arrested.
Interior Minister Jan Hamacek later told Czech radio that what he called “a huge tragedy” appeared to have been the culmination of a long-running conflict between neighbors.
The region’s fire chief Vladimir Vlcek told Czech TV that the blaze had spread very quickly.
“The fire developed very quickly, which is not normal. A fire like this usually affects a room, but this one has affected the whole apartment, all the rooms are burned ”.
