Emphasising that Congress is not into "politicising" terror, Prime Minister Manmohan Singh [Images] on Monday sought cooperation of all political parties in fighting the "serious problem" of terrorism.

Addressing an election rally in Hanumangarh, Rajasthan, the prime minister asked people to raise above religious and linguistic differences to fight the menace.

"I want to tell you that Congress will not indulge in politicising of terrorism. I wish all parties should join hands to help fight terrorism," Dr Singh said.

Noting that terrorism is a "serious problem" faced by the country, he said this was the time for the country to think above religious, linguistic and regional differences.

"This is the time to prove that no matter whichever state we are from, whichever religion we belong to, whatever is our language and whatever our customs and practices, we are first Hindustanis," the prime minister said.
