"Why has national leadership of BJP not condemned the attack on Rahul Gandhi's car (sic)?," he wrote on Twitter.
"Abuse, false charges, suppression of protests and now violence: nevertheless, BJP will not succeed in making Congress-mukt Bharat (sic)", the former Union finance minister wrote in another tweet.
Earlier in the day, the Congress accused the BJP-RSS of being behind what it described as a "murderous attack" on its vice-president in Gujarat's Banaskantha district and claimed that it was a "pre-planned conspiracy".
The Congress vice-president was also shown black flags and had to cut short his visit to the flood-hit areas of the state.
