The only gunman who survived the terror attacks in Mumbai in 2008, after taking part in the killing spree that left 52 people dead in the city's main train station, has been hanged in India.
Pakistani Mohammad Ajmal Amir Kasab was executed in prison in Pune early on Wednesday, India's Home Ministry confirmed to the BBC.
The Pakistani government had sent a plea for clemency to Indian president Pranab Mukherjee, which was rejected earlier this month.

Aged 21, Kasab and an accomplice opened fire in the main railway station, but dozens of places were targeted in the country in a 60-hour siege in November 2008, in a co-ordinated series of bombings and shootings.
In total, 166 people died across the city, including in luxury hotels, the Taj Hotel, Trident Hotel and a Jewish cultural centre.
Maharashtra home minister RR Patil told the Associated Press Kasab was hanged in the Yerawada prison at 7.30am.
He said: "This is a tribute to all innocent people and police officers who lost their lives in this heinous attack on our nation."
Senior officials in Delhi said Kasab's family members had been informed about the execution "through a letter sent by courier".
Home minister Sushil Kumar Shinde said he had signed Kasab's execution order on 7 November.
"We kept secrecy. It was important to maintain secrecy in this matter," Shinde told the BBC, and said Pakistan had been informed of the execution.
