Around 30 per cent votes were cast in the first three hours of polling in Nagaland, where election is on for its 60-member House today amidst unprecedented security.

Election is, however, being held for 59 seats today following the sudden death of Congress candidate P Chuba Chang of Teunsang sadar seat here yesterday.

The Election Commission has adjourned the polling in the constituency for a later date. Official sources said no untoward incident was reported from any part of the state, where two persons were killed and two others injured in poll-related violence in Tuensang and Wokha districts.
