The Iranian capital has a rat problem, and officials are resorting to firepower to solve it.
Twenty-six districts of Tehran are overrun with the rodents. Of particular concern are Norwegian rats, which can grow up to 16 inches long and have aggressive tendencies to match their large size.
During daylight hours, the Iranians use more conventional methods to cull the rodent population; namely, poison. But at night, they bring out the firepower. Officials use 'computer software' to track rat hotspots, and then send fire teams armed with air guns and infrared lenses to kill the rodents.
So far, 2,205 rats have been killed, their bodies incinerated or buried in designated dumps. As of yet, the effectiveness of this new military style campaign has yet to be assessed, but that hasn't stopped officials with Iran's environmental services from making plans to outfit 40 more fire teams by the end of this year.
