At least four people were killed Saturday amid reports of large-scale election fraud during voting in Bihar, India's most lawless state.
Election-related violence also was reported elsewhere in India during the fourth of five rounds of voting for a new federal parliament.
The deaths in Bihar were far less than the 39 killed in last week's polling there. This time, 75,000 police, reservists and soldiers were sent to prevent seizure of ballot booths, militant attacks and fighting between political supporters.
Fifty-one percent of the 80 million people eligible to vote Saturday cast their ballots in nine states. Voting is now completed in 418 of India's 534 parliament districts.
An exit poll on state TV showed Prime Minister Atal Bihari Vajpayee's Hindu nationalist National Democratic Alliance of 22 parties beating the Congress Party.
