India executes Mumbai bomb plotter Yakub Memon

India has executed Yakub Memon, the man convicted of financing the deadly 1993 Mumbai bombings, the BBC quoted the Maharashtra state authorities as saying Thursday.

Memon was hanged at a prison in Nagpur in the western state.

The serial blasts killed 257 people, and were allegedly to avenge the killing of Muslims in riots a few months earlier.

India rarely carries out death sentences - only three people have been executed since 2004.

There was tight security around the Nagpur prison on Thursday morning, and in parts of the state capital, Mumbai.

The March 1993 blasts targeted a dozen sites, including the Bombay Stock Exchange, the offices of national carrier Air India and a luxury hotel.
