Yemen unrest: Three die in Sanaa clashes

At least three people were killed and 15 others injured in Sanaa after pro-Saleh tribesmen arrived at a barracks occupied by mutinous troops.

There has also been renewed violence in the city of Taiz, where at least 15 people died on Monday.

The European Union has said that a transition of power must begin now.

More than 100 have died since protests against Mr Saleh began in February.

Protesters are calling for the president to step aside after 32 years in power, but he has signalled he has no plans to leave immediately.

A BBC correspondent in Sanaa says the number of protesters there is growing and they have erected tents in the road leading to the president's official home, about 13km (eight miles) away.

In Taiz our correspondent says gunmen in plain clothes have been seen firing from rooftops towards protesters in the city's Tahrir Square.

A doctor in Taiz told BBC Arabic that dozens of injured protesters had arrived at the hospital with gunshot injuries.
