India ? A bomb tore through a moving train in India’s remote northeast Thursday, killing five passengers and wounding four others, officials said. A little-known militant group claimed responsibility for the attack.

The New Delhi-bound high-speed Rajdhani Express had started from the eastern town of Dibrugarh in Assam state and had just crossed a station near Chungajan when the bomb exploded, said T. Rabha, an Indian Railway spokesman.
