Al Jazeera reports that Israeli attacks have killed at least 74 people in Gaza since dawn, including 56 Palestinians seeking humanitarian aid in Khan Younis. Many were killed by Israel tank fire. On Monday, another 38 aid seekers were killed, fueling growing international condemnation of the shadowy U.S.- and Israel-backed aid operation Gaza Humanitarian Foundation. Anna Halford of Doctors Without Borders described the operation as “neither a humanitarian enterprise nor a system. This is basically lethal chaos.” U.N. human rights chief Volker Türk has accused Israel of “inflicting horrifying, unconscionable suffering on Palestinians.”
