At least 16 people are dead and 58 injured in a head-on train crash in Poland late last night, the AP reports. A train traveling south from Warsaw to Krakow was accidentally put on the wrong track; train maintenance was being carried out on one of the tracks in the area at the time, notes the Guardian. "It is more dramatic than the pictures show. This is our most tragic rail disaster for many years," says Prime Minister Donald Tusk. "There are several dozen wounded and this may increase. People have been killed—this is the most tragic information." One American is among the dead. (More Poland stories.)
