Clipped to me from Israel National News:

“The IDF searched the boats for arms immediately after the takeover. The soldiers were forced to use tear gas after they were attacked with knives and cudgels, putting their lives in danger. Unofficial reports that ten persons have been killed and another ten wounded were admitted to Rambam Hospital in Haifa were changed by the Arab television station Al Jazeera to two killed and four wounded. The IDF has not corroborated any numbers.”
