The videos show bomb disposal teams carrying out controlled explosions, which send plumes of orange smoke into the air.

There have been multiple reports that IS has been deploying chlorine gas since late last year, but Iraqi officials say their footage confirms its use.
Haider Taher, from the Iraq Bomb Disposal Team, said troops have defused dozens of devices containing chlorine as part of the offensive against the militants.
