The head of the World Food Program, Cindy McCain, told ABC News that staffers on the ground were reporting people killed and called it a “tragedy.”“Aid distribution has become a death trap,” the head of the United Nations

, Philippe Lazzarini, said in a statement.In a separate statement, Israeli military chief of staff Lt. Gen. Eyal Zamir ordered that more aid sites be established — and that troops’ ground operation be expanded in unspecified parts of northern and southern Gaza.on crowds near the foundation’s sites. Before Sunday, 17 people were killed while trying to reach them, according to Zaher al-Waheidi, head of the Gaza Health Ministry’s records department.

The foundation says private security contractors guarding its sites have not fired on crowds. Israel’s military has acknowledged firing warning shots on previous occasions.The foundation said in a statement it distributed 16 truckloads of aid early Sunday “without incident,” and dismissed what it described as “false reporting about deaths, mass injuries and chaos.”

U.N. agencies and major aid groups have refused to work with the new system, saying it violates humanitarian principles.

Thousands of people headed toward the distribution site hours before dawn. As they approached, Israeli forces ordered them to disperse and come back later, witnesses said. When the crowds reached the Flag Roundabout, around 1 kilometer away, at around 3 a.m., Israeli forces opened fire, the witnesses said.“We prayed, we talked to people, we gathered information, and we eventually decided that this was the way we were going to go,” her husband added.

Within six months, the team at Children’s Hospital of Philadelphia and Penn Medicine, along with their partners, created a therapy designed to correct KJ’s faulty gene. They used CRISPR, the gene editing tool thatin 2020. Instead of cutting the DNA strand like the first CRISPR approaches, doctors employed a technique that flips the mutated DNA “letter” — also known as a base — to the correct type. Known as “base editing,” it reduces the risk of unintended genetic changes.

It’s “very exciting” that the team created the therapy so quickly, said gene therapy researcher Senthil Bhoopalan at St. Jude Children’s Research Hospital in Memphis, who wasn’t involved in the study. “This really sets the pace and the benchmark for such approaches.”In February, KJ got his first IV infusion with the gene editing therapy, delivered through tiny fatty droplets called lipid nanoparticles that are taken up by liver cells.
