A series of bomb explosions has killed at least 64 people in India's north-eastern state of Assam. At least 18 blasts caused the deaths and injured more than 300 others. The majority of them occurred in the state capital, Guwahati.
The nationalist United Liberation Front of Assam (Ulfa) denied responsibility for the blasts and stated that Indian "occupation forces" were liable for plotting them. There has been fighting for decades in Assam between security forces and separatist rebels. During the past 10 years, Ulfa has been held accountable for bombings targeting oil and gas pipelines, oil depots and regions occupied by migrant workers.
The blasts in Guwahati and the towns of Kokrajhar, Barpeta Road and Bongaigaon took place within an hour after 1100 local time. Four of the explosions tore through busy markets in Guwahati while three others were set off in the western town of Kokrajhar.
The first explosion killed 14 people outside the deputy commissioner's office in Guwahati. A further 22 were killed in the second blast at Ganeshguri close to the state secretariat and another four deaths were reported in Panbazar in central Guwahati.
Police sources added that 17 people died in the three explosions at Kokrajhar and five more in a further blast in the west of the state at Barpeta Road 81 miles from Guwahati. Details of one more blast were reported from near the oil refinery at Bongaigaon, between the towns of Kokrajhar and Barpeta Road.
The police were attacked with stones by enraged crowds after the blasts in Guwahati. A number of people were reported to have been injured in the clashes.
Two other north-eastern state capitals - Agartala in Tripura and Imphal in Manipur - saw serial explosions this month, killing at least 20 people and injuring more than 100 others.
