Tensions were high a day after two Palestinians were killed and 16 Israelis injured amid Palestinian anger at U.S. President Donald Trump's Middle East peace plan, unveiled last week with Israel's prime minister at his side.
There were sporadic clashes on Friday between Palestinian protesters and Israeli security forces near Azzun, where the funeral was held for the police officer killed in Jenin the previous day.
Palestinian authorities said he was killed by Israeli gunfire. Israeli officials did not comment, and Israeli media reported that he was shot by troops by mistake.
