Israeli forces have shot dead six Palestinians, four of them in a single incident, in one of the deadliest days in months of mass protests along the security fence separating Gaza and Israel, Gaza’s health ministry said. The ministry said four were killed in one location on Friday, where the Israeli military said it opened fire on a crowd of Palestinians who breached the fence and approached an army post. Israeli military spokesman Lt. Col Jonathan Conricus tweeted that one group had “detonated a bomb on the Israel-Gaza border fence”, allowing around 20 people to climb through the hole. He said around five of the group had then launched an organised attack against a military post inside Israel and all had been killed by the troops. Gaza medics said that, in addition to the dead, around 140 others were wounded. No Israeli troops were harmed, the army added. The Palestinian deaths bring to around 200 the number of Gazans killed since the border protests began on March 30, according to Palestinian Health Ministry figures. Since then Hamas has orchestrated near-weekly protests along the fence, pressing for an end to a stifling Israel-Egyptian blockade imposed since the militant group wrested control of Gaza in 2007.
