Officials say stray dogs entered the Sarajevo zoo, killed four kangaroos and injured another before guards could chase them away.

Zoo veterinarian Vedad Skapulj told The Associated Press that the dogs entered the kangaroo habitat in early Wednesday morning.

The canines apparently came from the forest searching for water, which is in short supply because a months-long drought has dried up local creeks.

The guards were able to save the life of the fifth kangaroo, which is now recovering. It is the last kangaroo at the zoo, which is located on Sarajevo's outskirts.

Skapulj called the incident a "tragedy." He says the zoo's management has wanted to get rid of some fences and modernize the facility but that stray dogs in the area have complicated those plans.
