In the wake of the attack on Congress leaders in Chhattisgarh, the Home Ministry on Monday asked all Maoists-hit states to revamp security of political workers and ensure that political activities are not affected by any violence.
In an advisory to Naxal-hit states, the Home Ministry said security of political leaders-- both national and regional parties-- should be reviewed thoroughly and, if necessary, their protection should be upgraded.
The Centre said there should not be any letup in the security of political leaders and whenever they travel or attend any function, adequate security should be provided.
The Home Ministry has asked the states to ensure that activities of political parties should not be hampered by threat, intimidation or violence by Maoists.
Heavily-armed Maoists had on Saturday ambushed a convoy of Congress leaders in the state's Bastar district, killing 27 people including PCC chief Nand Kumar Patel, his son Dinesh, Congress leader Mahendra Karma and ex-MLA Uday Mudliyar and injuring 32 others, including former Union Minister V C Shukla.
