Maoist rebels in the Indian state of Bihar have attacked a railway station, killing five policemen and a porter, officials say.
Police say that the rebels surrounded a police railway outpost at Jhajha railway station in Jamui district.
The rebels also looted arms and ammunition in the attack, police say.
Meanwhile police in the state of West Bengal say that three members of the ruling Marxist party have been shot dead by Maoists in a remote region.
The three leaders were killed in broad daylight in the state's remote Salboni region bordering the state of Jharkhand on Sunday.
Police said that a squad of 10 to 12 Maoists kidnapped seven political activists from Garmal village and took them to nearby jungle.
Three of those captured escaped, one was severely beaten up and the others - including a Communist Party of India (Marxist) branch secretary - were shot dead.
The CPI(M) has called for a day-long strike in the Salboni area to protest against the incident.
THIS IS WHAT HAPPENED DAY IN AND DAY OUT IN NEPAL BEFORE THE MAOISTS GRABBED POWER.
The Irony of it all: CPI(M) protesting Maoist violence. I hope the Maoists kill every CPI(M) candidate in Bengal. Then we the Indian security forces can kill them for killing elected politicians. That way both serpants leave the country side alone.
