Police say homemade bombs have exploded in parts of the Bangladeshi capital ahead of an anti-government general strike.

Police official Shah Alam says no injuries have been reported in Saturday's blasts in at least six spots in central Dhaka.

No one has claimed responsibility for the violence on the eve of Sunday's nationwide dawn-to-dusk general strike.

Police blame the blasts on opposition activists.

An alliance of 18 opposition parties, led by ex-premier Khaleda Zia, has called for the strike a day after the government raised the fuel price by about 9 percent.

The government says the hike was necessary to cut down subsidies on fuel.

The opposition says it will increase inflation.

In Bangladesh general strike is a common opposition tactic to highlight demands.
