A Nevada man who prosecutors say conspired to provide materials and support to co-conspirators to carry out terrorist attacks in India aimed at creating an independent Sikh state, Khalistan, pleaded guilty on Tuesday to federal charges.

Balwinder Singh, 42, made the plea in US District Court in Reno as part of an agreement with prosecutors, the Department of Justice said in a written statement.

Singh, who was arrested in December 2013, faces a maximum of 15 years in prison during his sentencing in February, although federal guidelines typically call for less time.

According to prosecutors Singh, also known as Jhaji, Happy Possi and Baljit, plotted terrorist attacks in India with several other people as part of a movement to create a Sikh state in the Punjab region.

Prosecutors said Singh bought two sets of night vision goggles and gave them to a co-conspirator who was planning to carry out the attack, which was thwarted when the man was prevented from boarding a flight to Bangkok at San Francisco International Airport.

Singh is a citizen of India and a permanent US resident, according to prosecutors.
