A Palestinian was killed in Israeli air strikes in the Gaza Strip on Friday. Confirming air strikes, the Israel Defence Forces said that it had targeted a Hamas-linked site in the northern Gaza Strip, a weapons-manufacturing warehouse in the central Gaza Strip and a weapons-smuggling tunnel in the southern Gaza Strip. Earlier on Friday, Israel lodged a complaint to the United Nations about rocket and mortar attacks launched from the Gaza Strip into southern Israel. Palestinian sources have described the strikes on Gaza as the heaviest since Israel's two-week offensive against Hamas a year and a half ago. No group in Gaza has so far claimed responsibility for the rocket fire. Hamas has said it is trying to stop militants from firing at Israel, but smaller groups have continued the attacks.
