The IDF officer was flown by helicopter to hospital in Beersheba on Tuesday shortly after he was seriously injured by Palestinian sniper fired from the Gaza Strip. A military spokesman said only that he was hit by rocks and the circumstances of his injury are being investigated. In reprisal, IDF tank fire was aimed at a Hamas position for the second time in a day. One Palestinian was killed. The first tank shelling was sparked by a Palestinian shooting attack on an IDF patrol.
