Palestinians fire Grad Katyusha rocket at Ashkelon; no wounded

Palestinians fired a Grad Katyusha rocket at Ashkelon Tuesday afternoon. There were no wounded reported. The rocket landed near a tennis court in the southern part of the city. Hamas vowed revenge after 17 Palestinians, amongst them the son of Hamas leader Mahmoud Zahar, were killed by the IDF in Gaza on Tuesday. Earlier, a volunteer from Ecuador was killed by a Palestinian sniper in a field near the Gaza perimeter fence.
