(USA TODAY) - Police in the Czech capital Prague say a building has been hit by a powerful explosion Monday, 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 on Divadelni Street. However, a natural gas explosion is strongly suspected.
The street is covered with rubble and has been sealed off by police.
Windows in buildings located hundreds of feet from the blast were shattered, the AP reported, including some in the nearby National Theater.
"There was glass everywhere and people shouting and crying," Vaclav Rokyta, a Czech student, told the AP near the scene.
"I was in the bathroom, no windows, the door was closed. Honestly, if I had been in my bed I would have been covered in glass," said Z.B. Haislip, a student from Raleigh, N.C.,, who was in a nearby building.
The mayor of Prague, speaking on the radio, said that three people may be trapped in the debris, the BBC reported.
