It came during mass protests as the United States opened its new Israeli embassy in Jerusalem .
The US move fulfilled a pledge by President Donald Trump, who has recognised the city as the Israeli capital, but it drew Palestinian anger and led to violent protests on the streets.
Palestinians have been using kites to drop the make-shift bombs on Israeli forces who responded by launching drones to unleash lung-burning tear gas on demonstrators.
At the embassy inauguration ceremony, Israeli Prime Minister Benjamin Netanyahu thanked Trump for "having the courage to keep your promises".
