Union home minister Sushil Kumar Shinde has said the Pakistan earlier had been informed that 26/11 terrorist Ajmal Kasab would be hanged on Wednesday.
"The President had rejected Kasab´s mercy plea on November 5. I signed it on the 6th and the Maharshtra government signed it on the 8th. The same day, we decided that he will be hanged on the 21st," Shinde said.
"We would have considered Pakistan´s request for the body, however, we have not yet received a request," he said.
Officials concerned had been asked to inform Kasab´s family about the hanging today.
Pakistan has reportedly said it respected India´s judicial process.
Maharashtra home minister R.R. Patil referred to Kasab´s hanging as a tribute to people and police officers who lost their lives during the attack.
Kasab was hanged at Pune´s Yerawada Jail at 7.30 am on Wednesday morning.
Maharashtra chief minister Prithviraj Chavan told a news channel that secrecy had been maintained over Kasab´s execution because the government did not want to compromise the security situation in any way.
A total of 166 people including foreigners were killed in the attack on Mumbai in 2008.
