A secretive military intelligence unit called IDF Unit 504 was key inunmasking Hamas’s abuse of hospitals for terror and hostage-taking, The Jerusalem Post reports. Unit 504 has received thousands of calls from Gazan Arabs wanting to help them against Hamas, apparently unhappy with the terror regime’s reign.
Unit 504 has interrogated over 300 Hamas terrorists, including those who had been in Shifa Hospital, where there were many Hamas forces disturbing the medical staff.
One terrorist estimated that he had seen between 80-100 terrorists at al-Shifa hospital. He added that Hamas and Islamic Jihad terrorists were “camouflaged” in the dress of various kinds of medical helpers, including using the emergency room for their activities.
According to Jerusalem Post, another Palestinian, Hamdoah Riad Assad Samlah, told how Hamas terrorists were using 50,000 Palestinian civilians at the large Palestine Red Crescent Society building in Gaza as human shields. He said that no one would resist Hamas or they might be killed.
Samlah said that Hamas wrapped their rockets in civilian blankets to hide them from the IDF and were frequently shooting from the nearby surroundings of the building.
