Four Qassam rockets were fired on Friday from the northern Gaza Strip into southern Israel. Rocket warning sirens were sounded around 11 p.m. in the Shaar Hanegev region and the southern city of Sderot. The IDFs initial investigation revealed that two of the rockets landed in an open area, while the other two exploded on the Gaza side of the border. No injuries or damage were reported. In response to the attack, the Israeli Air Force struck two Hamas military camps and two terrorist infrastructure sites early on Saturday.
