The government on Monday said it does not have inputs to suggest that the Naxals have established links with Pakistan's Inter-Services Intelligence agency.

"There are no inputs to suggest that the Naxals have established links with the ISI," Minister of State for Home Sriprakash Jaiswal told the Lok Sabha during the Question Hour.

He said as many as 217 security personnel and 441 civilians were killed in Naxal violence and action against them till November 30.

As many as 1435 incidents of Naxal violence were reported, Jaiswal said adding that 1,536 Naxalites [Images] have been arrested in the said period.

He sought information from a member on alleged links of some political parties with Naxalites in the affected states of West Bengal, Bihar, Jharkhand and Orissa.

Communist Party of India-Marxist member Mohammed Salim claimed in the Lok Sabha that some political parties in Naxal-affected states were harbouring Naxalites and demanded action from the government.

"We have no information on any political party sponsoring Naxalites. If you have any specific information, please give it to us for necessary action," Jaiswal said.

He said the Centre was taking steps to check the Naxal menace, which has emerged as a threat to national security.

The government will raise 10 Commando Battalions for Resolute Action (COBRA) in the CRPF as a specialised anti-Naxal force, Jaiswal said.

In a written reply to another question, Jaiswal said the government is further strengthening and streamlining the mechanisms for intelligence gathering and sharing with a view to make them more effective and result-oriented.

Steps are also being taken for modernisation and upgrading of the state police forces and their intelligence branches and providing modern weaponry, equipment and training to them.

In reply to a separate query, Jaiswal said according to information available, reports received and seizures made do not indicate increase in smuggling of drugs and weapons.

He said 14,626 people were arrested this year up to November under the Narcotics Drugs and Psychotropic Substances Act. Some 148 foreign nationals were also arrested under the Act, Jaiswal said.
