ISTANBUL — Israel is on high alert for a possible attack from Iran, following an airstrike that hit the Iranian consulate in Syria two weeks ago and killed several senior Iranian military officers. Iran blames Israel for the attack, and has vowed to retaliate.

Many countries have issued warnings to their citizens not to visit the region, as tensions flare and fears grow that an Iranian attack may be imminent — and the war in Gaza may spread.
