Four Indian soldiers are reported dead after India and Pakistan traded artillery fire across the line of control that divides Kashmir. An Indian policeman was also killed in a landmine explosion in Kashmir's Doda district.
Indian army officers say about 50-60 shells landed on their side of the line of control in Uri district, about 100 kilometers north of Srinagar, the summer capital of Jammu and Kashmir state.
To the south, in Jammu's Doda district, more than 90,000 security force personnel took up positions to safeguard polling for the final six seats in the 87-seat state assembly.
Tuesday's voting marks the last of four rounds of voting for the assembly. More than 600 people have died in election violence since campaigning began in August. Final results are expected to be announced on October 10.
Separatist militants say they will kill anyone campaigning or voting in the elections. Separatist political parties have urged a boycott.
Indian election officials say despite the violence turnout for the first three phases of voting was higher than expected, averaging about 40 percent. India accuses Pakistan of backing the militants a charge Islamabad denies.
