Some 99% of the incoming barrage was intercepted either outside Israeli airspace or over the country itself, Rear Adm Hagari said. They included all the drones and cruise missiles, which follow a flat trajectory, and most of the ballistic missiles, which are fired on an arcing trajectory that uses gravity to reach very high speeds. US President Joe Biden said US forces "helped Israel take down nearly all" drones and missiles launched by Iran on Sunday. In a statement, he said the US had moved aircraft and warships to the region before the unprecedented attack.
