Gandhi, at an election rally in Indore, Madhya Pradesh Thursday had said that an intelligence official had briefed him about 15-20 Muslim youth from riots-ravaged Muzaffarnagar district of the state as being in touch with Inter-services Intelligence (ISI) over killings of their brothers and sisters.
