Police in the Czech capital Prague say a building has been hit by a powerful explosion, injuring up to 40 people. Some people may still be trapped in the rubble.
Police spokesman Tomas Hulan told the Associated Press that it is not immediately clear what caused the blast in a building in Divadelni Street on Monday. A natural-gas explosion is suspected.
The street is covered with rubble and has been sealed off by police.
Windows in buildings located hundreds of meters from the blast were shattered, the AP reported, including some in the nearby National Theater.
The major of Prague, speaking on the radio, said that three people may be trapped in the debris, the BBC reported.
