Israel’s military has killed more Palestinian civilians in the Gaza Strip. Al Jazeera reports Israeli attacks have killed at least 25 Palestinians since dawn, including 11 people who burned to death inside their home in Khan Younis after multiple air attacks triggered a fire. Earlier today, the head of the U.N. agency for Palestinian refugees denounced Israel’s siege of Gaza, which is now in its 51st day. Philippe Lazzarini said nearly 3,000 trucks carrying lifesaving aid and basic supplies are prepared to cross into Gaza. He wrote, “Humanitarian aid is being used as a bargaining chip and a weapon of war.”
