WSJ News Exclusive | U.S. Relied on Intercepts in Assessing Hamas’s Operations at Gaza Hospital

WASHINGTON—The U.S. assessment this week that Hamas and other Palestinian militants were operating within Gaza’s largest hospital complex was based in part on intercepted communications of fighters inside the compound, people familiar with the matter said Wednesday. 

The signals intelligence, which was picked up in recent weeks, was among several pieces of U.S.-gathered information, the people said. And it was among the information that led the White House and Pentagon to announce Tuesday for the first time that the U.S. believed Hamas and Palestinian Islamic Jihad, also known as PIJ, were using Al-Shifa Hospital “as a way to conceal and support their military operations and hold hostages.”
