An Albanian town had to call in police and hunters after a pack of 200 stray mountain dogs attacked at least nine people. Headed by a clearly identifiable leader, the snarling pack overran the main street of the small northern town of Mamurras, its mayor said on Wednesday. "Even in the movies I have never seen a horde of 200 stray dogs from the mountains attacking people in the middle of a town," Anton Frroku said on Wednesday. He said the dogs bit at least nine people, aged from 20 to 60, dragging them to the ground and inflicting serious wounds.
