Tens of thousands of opposition supporters in Togo have marched in the capital, Lome in what they call the next phase of their campaign to force out President Faure Gnassingbe.

There were also big numbers of protesters in the second largest city of Sokode and the northern town of Bafilo, where youths blockaded a major highway connecting the north and south of the country.

Organisers had billed today's march as a "final warning" to the regime.

More rallies are expected on Thursday, described by organisers as a "march of anger", AFP news agency reports.

The main opposition leader, Jean-Pierre Fabre, said that they were going to maintain pressure on the government.

Protesters carried placards demanding the restoration of the 1992 constitution, which limited the number of presidential terms to two. Mr Gnassingbe is serving his third term in office.

He succeeded his father, meaning the same family has ruled Togo for 50 years.

At least four people have been killed and hundreds injured during weeks of anti-government protests in Togo.
