Security forces have seized 3,400-kgs of ammonium nitrate — used for making IEDs and explosives — and detonators during an anti-Naxal operation in Bihar’s Rohtas district.

The operation was conducted by paramilitary CRPF along with State police forces in the Rudrapur forests of the district.

“Numerous bags weighing 3,400-kgs of ammonium nitrate were seized during an operation in the district. Also, 700 electronic detonators were seized,” a senior official here said.

Thirteen large bundles of iron wire mesh were also seized during the same operation, the official added.

Ammonium nitrate is extensively used in Maoist violence-affected areas to prepare Improvised Explosive Devices (IEDs) to target security forces and hence such a large seizure of this chemical from one spot is worrisome, the official said.

The seized items will be handed over to local police.
