Former US congresswoman Cynthia McKinney arrives with fellow pro-Palestinian activists on the Gaza-bound boat in the southern Lebanese port of Tyre on December 30, 2008. An Israeli naval vessel collided today with the 20-metre (66-foot) Dignity carrying activists and medical supplies that was trying to break the blockade of Gaza, forcing it to head to Tyre in Lebanon. Passengers on board the the 20-metre (66-foot) Dignity said the Israeli patrol boat rammed their vessel, but Israel insisted the two boats collided as the Israeli navy was trying to contact its captain.
