Prime Minister Narendra Modi on Wednesday launched a scathing attack on Congress and its ally, the ruling DMK in Tamil Nadu, on Katchatheevu and `Shakti` remarks, accusing them of keeping the "country in the dark" over the island issue and charged them with ill-treatment of women.

He especially singled out the DMK over alleged corruption, saying the Dravidian party had the "first copyright" on the issue and added the "family" was intent on looting the state, in an apparent reference to the party`s first family, headed by its president and Chief Minister M K Stalin.
