A 62-year-old veteran sniper has killed at least 173 ISIS fighters in Iraq after he volunteered to join the fight against jihad in his home country.

A footage shows Abu Tahseen allegedly shooting and hitting a militant from the mountains in Iraq.

Mr Tahseen has fought in five conflicts and he is an expert in spotting the target and shooting it.

The pensioner talks about what his powerful weapon does to his targets saying it ‘pushes him back one meter before putting him down’, as Daily Mail reports.

He also talks proudly about how militants fear the area he defends with his gun saying: ‘You see this area – I guarantee to god no-one would come up it’.
