The top U.S. general made an unannounced visit to Israel on Friday to discuss “regional security challenges'' at a time of heightened tensions with Iran and its allies across the Middle East. Army Gen. Mark Milley, the Joint Chiefs chairman, met with senior Israeli military and intelligence leaders at an air base in southern Israel and held a video conference with Prime Minister Benjamin Netanyahu. The visit came days after an air raid on the Syrian capital, Damascus, suspected to have been carried out by Israel, killed five foreign fighters, including a member of the Iran-backed Hezbollah. The Lebanese militant group has vowed to retaliate for the killing of its fighters in Syria, and in recent days Israel has sent infantry reinforcements to its northern border with Lebanon. Earlier Friday, the Israeli military said an explosion on the Syrian side of the frontier damaged a building and a vehicle in the Golan Heights, which Israel seized from Syria in 1967 and later annexed. The military declined to provide further details. Recent weeks have also seen a series of mysterious explosions in Iran, including a blast at what analysts say was a nuclear centrifuge production facility. Milley's visit also came hours after a U.S. fighter jet passed near an Iranian passenger plane as it flew over Syria. Israel has long viewed Iran as its main regional threat because of its nuclear program _ which Tehran insists is for purely peaceful purposes _ as well as Iran's military presence in neighboring Syria and its support for armed groups like Hezbollah. Israel has carried out scores of airstrikes in recent years targeting Iran's military presence in Syria, where Tehran is a close ally of President Bashar Assad in the civil war. Israeli Defense Minister Benny Gantz said that in his talks with Milley, he emphasized “the need to continue the pressure on Iran and its proxies.” The Israeli military “is prepared and ready for any scenario and any threat, and I do not suggest our enemies to test us. We have no interest in escalation, but we will do all that is necessary to protect Israeli citizens,'' Gantz said.
