KASHIMPUR, Bangladesh: Bangladesh hanged three extremists including the leader of a banned militant outfit yesterday, after they were sentenced to death over a 2004 grenade attack on the British ambassador.

The authorities hanged Mufti Abdul Hannan, the leader of Harkatul Jihad Al Islami (HuJI), and one of his associates at Kashimpur prison just outside Dhaka and another associate in a jail in the northeastern city of Sylhet, home minister Asaduzzaman Khan said.

The three were sentenced to death in 2008 for the grenade attack four years earlier at a 14th-century Sufi shrine in Sylhet, which killed three people and injured the British high commissioner at the time. A madrassa teacher who studied in India and Pakistan, Hannan, 60, fought against the Soviets in Afghanistan before returning to join HuJI, a group founded for jihadists who fought in that war.
