Up to 10 people have been killed in clashes between Malawian protesters and police during a wave of riots against President Bingu wa Mutharka, health officials and relatives say.
Henry Chimbali, a health ministry official, told the Zodiak private radio station on Thursday that nine deaths had been confirmed in the northern city of Mzuzu.
Another man died after being shot in Blantyre, the commercial capital, his relatives told the Reuters news agency.
Rioters, protesting against mismanagement of the economy and a shortage of fuel, had ransacked the offices of Mutharika's Democratic Progressive Party (DPP) in Mzuzu on Wednesday, demanding he step down.
Police fired tear gas at the protesters in the capital, Lilongwe, on Thursday, a day after unprecedented nationwide unrest in the southern African nation, according to local radio station MIJ 90.3 FM.
But the situation in Blantyre was said to be returning to normal, with police clearing burning tyres left by protesters in the streets.
The protests were organised by the the Human Rights Consultative Committee, a group of more than 80 rights groups.
A police spokesman in Blantyre said they were still compiling a report on the rioting, which broke out after security forces tried to suppress the protests.
The decision to stop the protests was taken after a group calling itself Concerned Citizens announced a rival march in support of the government.
The authorities warned of "possible disruptions and undesirable incidents" but the protesters had already gathered in Lilongwe's city centre when they were told about the injunction stopping the demonstration.
When police tried to disperse the protesters, they went on the rampage in Ntchesi, said witnesses.
Businesses ransacked
A spokesman for the Human Rights Commission told the AFP news agency that about 400 people had gathered in Lilongwe to protest.
One witness said protesters ransacked two businesses owned by legislators belonging to the ruling Democratic Progress Party (DPP).
"The police were overwhelmed here by the crowd of people, although they finally suppressed the rioting crowd," Mike Chipalasa, a spokesman for the Human Rights Commission, said referring to the violence in Mzuzu.
"The demonstrators were just angry for being not allowed to march by police. They resorted to looting."
The opposition has denounced Mutharika for failing to smooth over a diplomatic row with Britain, after it suspended economic aid to its former colony.
Relations between the two countries were strained in April when a leaked British diplomatic cable accused Mutharika of "becoming ever more autocratic and intolerant of criticism".
Both countries have since withdrawn their ambassadors, while the UK last week suspended around $30.7m of budgetary aid meant for anti-poverty programmes in one of the world's poorest countries.
Mutharika's policies have included a ban on publications deemed "contrary to the public interest".
He has also imposed a requirement for activists seeking to hold protests to make a deposit of about $15,000 with police, intended as a safeguard against rioting and property damage.
