Thousands of Palestinians took to the streets of the West Bank and Gaza Strip for the fourth Friday in a row of riots over US President Donald Trump’s recognition of Jerusalem as Israel’s capital.

Palestinian health officials claimed at least 50 demonstrators had been wounded by live fire, mostly along the Gaza border. An Israeli military spokeswoman said soldiers had shot at the “main instigators” who she said posed a direct threat to the troops and who were trying to damage the border security fence.

The spokeswoman said about 4,000 Palestinians across the West Bank and Gaza, some throwing rocks and fire bombs and setting tires alight, confronted Israeli soldiers who responded mainly by firing tear gas.

In Gaza, protesters chanted “Death to America, death to Israel, and death to Trump,” and terrorists fired rockets into Israel, drawing strikes by Israeli tanks and aircraft.

The military said it targeted posts that belonged to Hamas, the Islamist group that controls the Palestinian coastal enclave, after intercepting two of the three rockets fired into Israel. Police said the third struck a building, causing damage. No casualties were reported in those incidents.
