A drone launched by the Palestinian militant group Hamas briefly infiltrated Israel on Monday before it was shot down an Israeli missile, according to the Israeli Defense Forces (IDF) and the Wall Street Journal. Its unclear whether or not the drone was armed, but the use of drones by Hamas marks a new front in the latest sustained outbreak of combat between Israel and Palestinian militants, in which Israeli airstrikes have reportedly claimed the lives of 172 Palestinians, according to the Palestinian Health Ministry in Gaza. Hamas and other Palestinian militant groups have reportedly fired over 971 rockets on Israel, though no fatalities have been recorded as a result.
