Kizza Besigye arrest prompts Uganda demonstrations

Police in Uganda have used tear gas and fired rubber bullets to disperse demonstrators angry about the arrest of the opposition leader, Kizza Besigye.

He was detained after going to join a fresh "walk-to-walk" protest against rising living costs. At least 12 other opposition leaders were arrested too.
The opposition campaign began last week and spread to several towns, at least three people were killed in clashes.
At the weekend, the president described the campaign as "idiotic" and illegal.
Correspondents say the government is desperate to ensure that large street protests do not take place.
Last week it tried to block popular social network sites on the internet.
Dr Besigye, who was arrested and shot in the hand in protests last week, lost to President Yoweri Museveni in February's election but says the poll was rigged.
He has been defeated by Mr Museveni in three presidential elections, gaining 26% to the president's 68% in February.
