Demonstrator displays a sign during a protest in Brussels

A demonstrator displays a sign reading “Boycott Israel, racist state” outside the Belgian foreign affairs building during a protest in Brussels May 31, 2010. Israel’s storming of a Gaza-bound aid flotilla set off a diplomatic furore, drawing criticism from friends and foes alike and straining ties with regional ally Turkey, which called off planned joint military exercises.
