The Beeb's Ben Sutherland looks at the World Urban Forum in Vancouver and, among the cries for "more power!", finds some workable ideas.

From the BBC:

The Islamist militia now controlling the Somali capital says it will protect foreign media following the murder of Swedish journalist Martin Adler.

Mr Adler, 47, was shot dead as he filmed a rally in Mogadishu on Friday.

The chairman of Somalia's Union of Islamic Courts, Sharif Sheikh Ahmed, sent condolences to Mr Adler's family and promised to track down the killer.

The rally was in support of Thursday's peace deal between the Islamists and the interim government.

Sharif Sheikh Ahmed said an office would be established to guarantee that international journalists could operate safely and effectively in Mogadishu.

He blamed forces that wanted to destabilise the capital and said: "The Islamic courts are very sorry for the killing and we send our condolences to the family and colleagues."  

Sharif Sheikh Ahmed was speaking hours being replaced at the head of the militia by a more radical figure, Sheikh Hassan Dahir Aweys - who is wanted by the US as a terror suspect.
