For example, here:
Nor has the Zionist terror machine hesitated to kill its own. In 1940, Menachem Begin's Irgun Zwei Leumi terrorist gang bombed the ship Patria in Haifa harbor, killing 240 Jewish refugees, (while blaming the British)...
In the first instance, Begin was still in Lithuania at the time and arrived in Mandate Palestine in April 1942, becoming Irgun commander in December 1943.
But, by that as it may, that operation was done by the Hagana and first revealed in English in Munya Mardor's book in 1964!
