Quote from Naeim Giladi an Iraqi Jew ...

"I began to find out about the barbaric methods used to rid the fledgling state(Israel) of as many Palestinians as possible. The world recoils today at the thought of bacteriological warfare, but Israel was probably the first to actually use it in the Middle East.
In the 1948 war, Jewish forces would empty Arab villages of their populations, often by threats, sometimes by just gunning down a half-dozen unarmed Arabs as examples to the rest. To make sure the Arabs couldn’t return to make a fresh life for themselves in these villages, the Israelis put typhus and dysentery bacteria into the water wells.
Uri Mileshtin, an official historian for the Israeli Defense Force, has written and spoken about the use of bacteriological agents. According to Mileshtin, Moshe Dayan, a division commander at the time, gave orders in 1948 to remove Arabs from their villages, bulldoze their homes, and render water wells unusable with typhus and dysentery bacteria.
Acre was so situated that it could practically defend itself with one big gun, so the Haganah put bacteria into the spring that fed the town. The spring was called Capri and it ran from the north near a kibbutz. The Haganah put typhus bacteria into the water going to Acre, the people got sick, and the Jewish forces occupied Acre. This worked so well that they sent a Haganah division dressed as Arabs into Gaza, where there were Egyptian forces, and the Egyptians caught them putting two cans of bacteria, typhus and dysentery, into the water supply in wanton disregard of the civilian population.
“In war, there is no sentiment,” one of the captured Haganah men was quoted as saying."
