The suspect was identified by the Israeli and Egyptian authorities as an Egyptian security officer. The deadly event may be connected to a thwarted drug smuggling attempt, the Israelis said.

Israel said the Egyptian border guard crossed into Israel and killed the three soldiers before he was fatally shot by troops.

Three Israeli soldiers and an Egyptian security officer were killed near the countries' border on Saturday, Israel and Egypt said, in an incident whose details remained unclear.

Israel said the Egyptian border guard crossed into Israel and killed the three soldiers before he was fatally shot by troops. Egypt said he had been chasing drug smugglers when he entered Israel.

The exchange of fire reportedly took place around the Nitzana border crossing between Israel and Egypt. The crossing is located about 40 kilometers (25 miles) southeast of the point where Israel’s border with Egypt and the Gaza Strip converge. It's used to import goods from Egypt destined for Israel or the Hamas-ruled Gaza Strip.
