JERUSALEM—Israel’s defense minister on Sunday rejected international calls for an investigation into deadly violence along Gaza’s border with Israel, saying troops acted appropriately and fired only at Palestinian protesters who posed a threat.

Fifteen Palestinians were killed and over 700 wounded in Friday’s violence near the Israeli border, according to Palestinian health officials. It was the area’s deadliest violence since a war four years ago.

Human rights groups have accused the army of using excessive force, and both the U.N. secretary-general and the European Union’s foreign policy chief have urged an investigation.

In an interview, Defense Minister Avigdor Lieberman said Israel would not cooperate with a U.N. inquiry if there were one.
