A rescue helicopter has crashed in Slovakia, killing four people on board, a health ministry spokesperson said.
The four -- a pilot, a doctor, and two rescue workers -- were killed yesterday while on their way to help a ten-year-old boy with a head injury, the health ministry said.
According to local media, the chopper's propeller was caught in an electrical wire, sending the helicopter crashing into the Hornad river, near Hrabusice village in eastern Slovakia.
