Clashes erupted along the Gaza Strip's border with Israel on Monday between Palestinians and Israeli forces ahead of the controversial inauguration of the US embassy in Jerusalem.
Gaza's health ministry said 12 Palestinians were wounded.
Several thousand had gathered near the border, while smaller numbers of Palestinians were approaching the fence, with Israeli snipers positioned on the other
side.
Larger crowds were expected to gather later in the day to protest the move of the US embassy in Israel from Tel Aviv to Jerusalem.
The embassy inauguration was due to occur at 4:00 pm (1300 GMT).
Fifty-four Palestinians have been killed by Israeli fire since protests and clashes began along the Gaza border on March 30.
No Israelis have been wounded and the military has faced criticism over the use of live fire.
