It’s been a dangerous night in Jerusalem and the Gaza Strip as Israel and the militant group Hamas launched airstrikes at each other. Hamas fired 7 rockets at Jerusalem and dozens more at southern Israel last night after violent clashes near the al-Aqsa Mosque in Jerusalem between Israeli police and protesters left more than 300 Palestinians injured. Israel has retaliated this morning with airstrikes on the Gaza Strip. Reports say 20 people were killed, including 9 children. Israel’s PM Benjamin Netanyahu said the counter-attack was necessary because the “terrorist organisations in Gaza crossed a red line”. It follows days of unrest ahead of yesterday’s Jerusalem Day march to mark the anniversary of Israel’s capture of East Jerusalem in 1967. Palestinians, who also lay claim to the land, considered the event to be a provocation. Experts say what has unfolded in the last few days is the worst violence Jerusalem has seen in years.
