The Israeli military has launched air raids on Gaza following clashes between its soldiers and Palestinian protesters.
The Palestinian health ministry said dozens of people were wounded, including a 13-year-old Palestinian boy who was shot in the head.
“Forty-one civilians were wounded with various injuries,” the ministry said in a statement.
The Israeli military called the protesters “rioters” and said some had tried to climb the border fence and hurled “explosive devices” at its soldiers.
The military said it “responded with riot dispersal means, including when necessary live fire” and added that an Israeli soldier was “critically injured by live fire emanating from Gaza”.
Hamas and other groups in Gaza issued a joint statement in which they “saluted the heroic youth” who clashed with Israeli forces.
The violence was some of the worst since a deadly assault by Israel on the Gaza Strip in May.
The new Israeli government, headed by Naftali Bennett, had blocked aid from Qatar, calling for a mechanism to ensure Hamas does not benefit from the cash.
However, Israel has announced an agreement with Qatar to resume aid payments to thousands of families in the Gaza Strip.
Under the new arrangement, the funds are to be transferred by the UN directly to Gaza families, while giving Israel oversight over the list of recipients. The payments are expected to begin in the coming weeks.
