I n a letter dated March 12, Army Chief General V K Singh has warned Prime Minister Manmohan Singh that the country's security is at risk.

The letter states that Indian army tanks have run out of ammunition, and emphasises on overcoming the shortcomings, and bring the army to fighting level.

Singh also calls almost 97 per cent of the air defence as obsolete, and the elite special forces are short of weapons.

Recently, Singh, who has claimed that he was offered a bribe of Rs 14 crore for clearing a 'sub-standard' procurement order, has said he could not understand the import of the statement and that is why he did not act against the person who made it.
