This clip is in Hebrew. It's about the Marine Carp a ship carrying Americans and others on their way to (then) Palestine. The ship stopped in Beirut, was boarded and the Jewish men were taken off and imprisoned in Ba'albek.
One of the passengers, Muriel Arens, a Betaria from the US and wife of Misha Arens who became Minister of Defense and Foreign Minister of Israel, was on that ship as well.
The women were allowed to continue to Haifa and eventually the men were released, sent back to the US but not allowed to enter and then sent back to Haifa (this time without stopping in Beirut).
