Israel has accused Iran of fuelling recent violence on the Gaza border that has seen more than 100 Palestinians killed amid protests against Israel.
Israeli military aircraft dropped leaflets on Gaza on Thursday, warning Palestinians not to approach the border fence for their own safety.
The leaflets urged people not to become “a tool” of the militant group Hamas, which dominates Gaza, alleging that its agenda was driven by Iran.
Fresh protests are planned for Friday.
It will be the last Friday of the Islamic holy month of Ramadan and also al-Quds (Jerusalem) Day in Iran, when demonstrations are held against Israel.
Some 123 Palestinians have been killed by Israeli forces and thousands more wounded since a protest campaign began on 30 March, Gaza’s health ministry says.
