Police say that a 4-year-old boy has died and his 6-year-old brother was injured after they were attacked by a pack of stray dogs outside a park in Romania.

Police spokeswoman Emilia Mihai said Monday they boys had gone to the park earlier Monday with their grandmother, and were attacked after the two of them wandered out of the park on their own.

Mihai said police found the 4-year-old's body in a bush.

Authorities say 1,100 people were bitten in Bucharest by stray dogs in the first four months of 2013.

Romania's capital is home to thousands of stray dogs. In 2006, a Japanese tourist was killed by a stray dog. In 2011, a woman also died after being attacked by a pack of dogs in a hospital courtyard.
