About 20 houses have been burnt down in riots by cashew nut farmers and other protesters in southern Tanzania, the local MP has told the BBC.
Faith Mitambo said two buildings at her home in Liwale town had been set alight and that other houses targeted belonged to members of the ruling CCM party.
The trouble began after payouts being made to farmers for their crop were less than the price agreed last year.
More police have been deployed to the region to stop further unrest.
Ms Mitambo, who was in the capital, Dodoma, at the time, told the BBC Swahili service she was travelling down to her constituency to assess the situation.
She had been told the protests, involving groups of young men, began in villages on Tuesday morning and reached Liwale town by the evening.
A resident of Liwale told the BBC that on Wednesday there was a sense of fear in the town and police had fired tear gas in the market to stop crowds gathering.
