Details on the mass shooting at a Texas elementary continued to emerge yesterday, with officials saying all 21 victims—19 children and two adults—were all part of the same classroom in which the gunman had barricaded himself. At least 17 more people were injured from the attack, officials said. See the list of victims known so far here.
The 18-year-old suspect reportedly warned about his plans in the hour leading up to the attack, later posting he had killed his grandmother and was heading to the elementary. The shooter, a student at the town's high school, used an AR-15 style semiautomatic rifle, which was one of two rifles he legally bought shortly after his birthday and just days before the attack. A motive still hasn't been determined.
A team of federal and local law enforcement officers killed the suspect. Other officers on the scene were unable to do so after the shooter barricaded himself; they turned to breaking windows to help other teachers and students escape.
The killings have reignited debates over gun control legislation, though Majority Leader Chuck Schumer (D-NY) said yesterday he would not immediately bring a bill to the floor for a vote. A prayer vigil for the victims was held last night.

Nuclear Talks Hit Snag
President Joe Biden is keeping Iran's Islamic Revolutionary Guards Corps on a list of foreign terrorist organizations, according to officials. The decision could complicate international efforts to restore a 2015 deal meant to restrict Iran's nuclear activities in exchange for sanctions relief. Lifting the IRGC's 2019 terrorist designation (see background) has been a precondition for Iran to return to talks with global leaders, who have been working on reviving the deal for over a year amid rising tensions between Arab nations and Iran-allied groups.
The US withdrew from the Iran nuclear deal (see 101) in 2018 after former President Donald Trump said he would reimpose sanctions on Iran's oil sector, claiming the deal wasn't enough to curtail Iran's nuclear program. Since then, Iran has begun escalating its nuclear activities.
The US envoy for Iran told lawmakers yesterday the chances of renewing a deal were tenuous as the Biden administration attempts another shot at brokering an agreement.
Scientists have demonstrated for the first time the ability to teleport quantum information across points in a network not physically connected to each other, according to research released yesterday. The advance marks a key step forward in the development of a scalable quantum internet.
The technology relies on a phenomenon known as quantum entanglement, which effectively links the state of separate particles—for example, which way a particle is spinning—into a collective super-state (go deeper). Typically, quantum information can be passed through fiber optic cables via light particles, a method that incurs a significant loss as the light bounces around inside the cable.
Because there is no physical medium when particles become entangled, the method allows information to be passed without loss—critical for future networks involving thousands of quantum computers. The experiment successfully demonstrated the technique across three separate nodes.
