Striking taxi drivers erected barricades at border crossing points and paralyzed traffic in Budapest and other major cities Friday in a protest against a sharp rise in gasoline prices.

Police in the capital evacuated the Industry and Trade Ministry building and cordoned off a subway station following two separate bomb threats believed linked to the strike. No explosives were found.Taxi drivers around the country walked off the job Thursday night and began setting up roadblocks in spontaneous protests early Friday after the government imposed price increases of up to 70 percent for gasoline.

Talks between the drivers and government officials began early Friday with little progress reported, amid demands by the workers for a temporary suspension of the price hikes while negotiations continued.
