Security for Congress president Sonia Gandhi has been further tightened following intelligence inputs suggesting threat to her life from Pakistan-based militant outfits including the Al-Qaeda.
The intelligence inputs have been shared with elite Special Protection Group (SPG) guarding her.
While she was already protected by the SPG, the authorities have now decided to stop traffic when she is moving anywhere in the country as a precautionary measure.
Sources said that some militant outfits, including the Al-Qaeda, were trying to target her. The threat was based on intelligence inputs.
