"I welcome it. Now the government of India should pursue the case against the handlers in Pakistan. They should expedite the decision on Afzal Guru," said party General Secretary Digvijay Singh.
Kasab, the sole surviving terrorist from the 26/11 terror attack, was hanged to death at the Yerawada Jail in Pune at 7.30 am.
Information and Broadcasting Minister Manish Tewari said the law has taken its own course in the case.
"A dastardly terrorist act was perpetrated. An investigative process that culminated in a multi-layered fair judicial process playing itself out right up to the Supreme Court, the law has taken its own course," Mr Tewari said.
166 people had died in the 26/11 terror attack. Police had succeeded in capturing Kasab alive after killing the remaining nine terrorists.
