From the NYT, Suicide Bomber Kills Kandahar Mayor:
Mr. Hamidi had launched a contentious campaign to destroy illegal homes in northern Kandahar city. The campaign was strongly resisted by the people who lived there, many of whom had been there for years. A day earlier, there had been a protest and the mayor agreed to meet with the protesters on Wednesday.
The bomber entered the mayor’ s compound with the protesters’ delegation, said Mr. Ayoubi, a spokesman for the Kandahar provincial governor, Toorylai Wesa.
“Illegal homes” goes undefined.
