Indian troops killed in explosion
Four paramilitary troops have been killed in an explosion in India's northeastern state of Assam, officials said.
Four other troops and 20 civilians were injured in the blast that hit a security convoy at Dhalukdubi in Goalpara district bordering Bangladesh.
Officials said that an 'indigenous' explosive device caused the blast.
Assam's main rebel group, United Liberation Front of Assam (Ulfa), has claimed responsibility.
The Ulfa rebels have fought for a separate Assamese homeland since 1979.
Friday's explosion hit a convoy of the Central Reserve Police Force that is deployed largely for counter-insurgency duties across India's troubled regions.
Muslim migrants from Bangladesh comprise the majority of the people of Goalpara.
