(JTA) — An Israeli airstrike destroyed a Hamas facility south of Gaza City in a retaliatory attack. The strike on May 6, in which a missile was launched at a Hamas watch post, followed the targeting from the Gaza Strip of soldiers patrolling the fence along the southern part of the Gaza Strip, Army Radio reported. The firing of two mortar rounds at Israeli troops resulted in no injured and no damage. Last Friday’s strike was the third time in three days that Israel has retaliated for mortar attacks from Gaza. One woman was killed May 5 during one such attack, according to Palestinian sources in Gaza. At least 16 mortar rounds were launched into Israel from Gaza last week – double the number recorded in the previous four months. On May 5, the IDF said it had uncovered a tunnel from Gaza leading into Israel, whose function was to enable terrorist attacks on Israeli soil. Stretching for hundreds of yards, the tunnel was 90 feet underground, according to the IDF.
