An international flotilla carrying pro-Palestinian activists and 10,000 tones of humanitarian aid left Cyprus Sunday, on what organizers hope will be the last stage of their attempt to break Israel's siege of the Gaza Strip. "The flotilla plans to halt in international waters, in order to arrive off the Gaza coast Monday morning," Audrey Bomse, spokeswoman of the Free Gaza organization," told the German Press Agency 'DPA'. "We don't want to arrive in the dark," she said. The flotilla had planned to arrive in Gaza over the weekend, but at least two boats experienced technical problems.
