Israeli, left, and Egyptian flags flutter in the wind at the border post between the two countries.

Israel has reopened its border crossing to Egypt’s Sinai Peninsula shut over a week ago over intelligence warnings of possible attacks.

Israel’s counterterrorism office said on Friday the Taba crossing is reopened but warned that the threat to Israelis in Sinai remains “severe, concrete and immediate.”

It recommended against visiting Sinai now and advised those already there to “leave immediately.”

Israel shut the border a day after militants in Egypt bombed two churches earlier this month, killing dozens of Christian worshippers during Palm Sunday ceremonies.

Earlier this week, the Islamic State group claimed responsibility for an attack that killed a policeman and wounded at least three in Sinai, near a tourist area along the Red Sea coast.

Sinai is popular with Israeli tourists for its pristine beaches and coral reefs.
