Wild boars gather in a residential area in the northern Israeli city of Haifa on December 5, 2019.

The pigs have long entered the city at night looking for food and water but residents say in recent months they have been increasingly brazen – standing in the middle of streets without fear, digging up public gardens and even overturning large refuse bins.
