Shimla, Jan 10 (Agencies): Stressing that corruption has become a menace in the country, the All India Anti-Terrorist Front on Monday announced that it would observe January 30, the death anniversary of Mahatma Gandhi as 'anti-corruption day'.

Corruption had become biggest threat for the country as political parties, bureaucracy and anti corruption agencies have become 'immune' to this menace, President of the Front, Maninderjit Singh Bitta told reporters.

"Only a strong people's movement could help check corruption and the purpose of observing the anti-corruption day was to focus on the issue," Bitta said.

Describing China as biggest threat to India, Bitta said that it has developed bases in all the neighbouring countries, constructed railway lines along Tibet border.

Bitta alleged that the government was playing vote bank politics and by allowing the execution of death sentence of Afzal Guru and Kasab to hang on.
