Two rockets fired from Egypt's Sinai peninsula struck Israel's Red Sea resort of Eilat on Wednesday, causing no casualties or damage, the Israeli military said.
The incident was likely to fuel Israeli concern about lawlessness in neighboring Sinai, where Islamist militants have stepped up their activities since Egyptian President Hosni Mubarak's downfall in 2011.
An Israeli military spokeswoman said two rockets were launched from Sinai and that both hit open areas. Israeli television showed the casing of the one of the rockets lying in sand at a construction site in Eilat.
Israel deployed an Iron Dome anti-rocket battery in Eilat some two weeks ago, a period coinciding with the Jewish Passover holiday when the city at the tip of Gulf of Aqaba is packed with vacationers.
But on Wednesday, the system did not intercept the incoming missiles "for operational reasons," the spokeswoman said, without elaborating.
In the Sinai, Egypt's military carried out search operations after the attack, which was launched a day after Israel celebrated its 65th anniversary.
"It is not yet clear where the rockets were fired from," an Egyptian military source said. "Investigations are still ongoing, so it is too early to tell."
Rockets last struck Eilat in November, again causing no injuries or damage.
Israel's Army Radio reported on Wednesday that a rocket had also hit the nearby Jordanian city of Aqaba, but a spokesman for the Jordanian Civil Defence denied the suggestion.
