Reacting on the controversy over his "cattle class" remarks, Minister of State for External Affairs Shashi Tharoor Thursday night said he was "sorry" for hurting any sentiments and that his words had been misunderstood.

Tharoor ran into trouble for a message he posted on the social networking site Twitter in which he said sarcastically in response to a query that he would travel "cattle class out of solidarity with all our holy cows!".
