The military said 20 of the hostages had been killed during the 11-hour standoff.
Condemning the terror attack in Bangladesh capital in which 20 people were killed, Congress president Sonia Gandhi and party vice president Rahul Gandhi today pitched for "collective and decisive" action against those behind the strike.
Expressing deepest condolences to the families of those killed, Ms Gandhi called for immediate collective and decisive action against those who are behind these attacks in Dhaka.
"Congress stands firmly with people of Bangladesh in these testing times," she said, adding that such attacks are "contradiction of all ethical and human values".
"Strongly condemn the #Dhaka attack. My prayers are with the people of Dhaka and B'desh. This senseless violence must be fought strongly & unitedly," Mr Gandhi said in a tweet.
Twenty foreigners, including an Indian girl, were hacked to death by suspected ISIS terrorists inside a cafe popular with expatriates in Dhaka's diplomatic zone in the worst terror attack in Bangladesh before commandos launched an assault today killing six attackers and capturing one alive.
