The Israeli army has gone on high alert along the border with the Sinai peninsula as Egyptian forces hunt for suspected members of the Lebanese Hezbollah militia, a senior official said on Tuesday.
Israeli and Egyptian authorities are holding "regular security updates" after officials in Cairo said a 13-member Hezbollah cell being hunted down in the Sinai was plotting attacks on Israelis, the security official told AFP.
"The army was ordered to go into a high state of alert along the border with Egypt following the developments in Egypt and Sinai," he said.
Israeli security authorities fear the Shiite militia was also planning attacks inside Israel or along the 200-kilometre (125-mile) border, he said.
Israeli authorities have urged its nationals to leave the Sinai, a popular destination for Israeli tourists during the Jewish Passover holiday.
