Indian authorities say a string of bomb attacks in the northeastern part of the country has left at least one person dead and four wounded.
Police say the blasts on Wednesday occurred in different parts of the remote Assam state, including a series of attacks in the state's capital, Guwahati.
They say a policeman was killed when he tried to defuse a bomb planted in a busy market in a western Bongai-gaon district.
The militants also blew up a section of a gas pipeline in eastern Assam, causing a fire but no casualties.
No one has claimed responsibility for the attacks. However, police blame rebels from a separatist group known as the United Liberation Front of Asom. It has been fighting for an independent homeland since 1979.
