Explosion in Prauge Injures Dozens, April 29, 2013

From the Guardian:

A powerful explosion has damaged a building in the centre of the Czech capital, Prague, injuring up to 40 people. Authorities said they believed people were buried in the rubble.

Police spokesman Tomas Hulan said it was not certain what caused the blast in Divadelni Street, in Prague's Old Town, at about 10am, but it was likely to have been a natural gas explosion.

The street was covered with rubble and had been sealed off by police, who also evacuated nearby buildings and closed a wide area around the site of the explosion.

Zdenek Schwarz, head of the rescue service in Prague, said up to 40 people were injured, at least four of them seriously.
