Family members and “non-emergency U.S. government personnel” were ordered by the State Department to leave Lebanon on Sunday, June 22, after three nuclear sites in Iran were attacked by the United States military on Saturday. State Department officials cited the “volatile and unpredictable security situation in the region” as the reason for the alert.

In addition, travel warnings were issued for Saudi Arabia and Turkey. The U.S. Mission to Saudi Arabia was advised to exercise “increased caution” and limit “non-essential travel” to any military installations, and the same recommendation was given to U.S. citizens in the Kingdom as well. Mission staffing and operations remain the same and consular services are continuing.

The State Department said government personnel in Turkey should keep a low profile and avoid personal travel to the U.S. Consulate in Adana.

“Negative sentiment toward U.S. foreign policy may prompt actions against U.S. or Western interests in Turkey,” the department said. “In the past, such activities have included demonstrations, calls for boycotts of U.S. businesses, anti-U.S. rhetoric and graffiti.”

While the U.S. Mission in Iraq already started evacuating some employees on June 12, more left the country on Saturday, June 21 and Sunday, June 22. Both the U.S. Embassy in Baghdad and Consulate General temporarily suspended routine visa services, but they will provide others services. A State Department alert warned of “increased potential for foreign terrorist organization-inspired violence” or attacks on U.S. businesses and locations frequented by Americans.

According to a State Department document seen by the Associated Press, 67 American citizens left Israel on two government flights for Greece on Saturday, June 21, with four more flights to Athens planned initially for Sunday, June 22. Since Israeli airspace closed after the American airstrikes, though, three of the four flights were canceled, the U.S. Embassy in Jerusalem said. The rescheduled flights are set for Monday, June 23. Up to six evacuation flights to Greece are expected, as well as a chartered flight to Rome, and another to Cyprus, the AP said.

The document also shows a cruise ship with more than 1,000 U.S. citizens on it, including what the AP described as “several hundred Jewish youngsters” visiting Israel on a tour arrived in Cyprus.

As of Saturday, more than 7,900 Americans had asked for assistance in leaving Israel and more than 1,000 had sought help in leaving Iran, where the U.S. has no diplomatic presence, the document said.

About 700,000 Americans, many of whom are dual citizens, are in Israel, the Associated Press said. Thousands of Americans are in Iran, most with dual U.S.-Iranian citizenship.

Department of Homeland Security warning

A Sunday, June 22 bulletin sent out by the Department of Homeland Security said there’s a “heightened threat environment.” There are currently no specific credible threats against the U.S., DHS noted. Still, it warned that “low-level cyber attacks against U.S. networks by pro-Iranian hacktivists are likely.” Cyber actors with ties to the Iranian government could conduct attacks against United States networks, the department added.

“The likelihood of violent extremists in the Homeland independently mobilizing to violence in response to the conflict would likely increase if Iranian leadership issued a religious ruling calling for retaliatory violence against targets in the Homeland,” the bulletin said.

Global reactions to US strikes on Iran nuclear sites

Countries that are part of the United Nations Security Council met on Sunday, June 22 to talk about the conflict between Israel and Iran. Some urged de-escalation and expressed concerns about what would happen if the situation gets worse.

“The bombing of Iranian nuclear facilities by the United States marks a perilous turn in a region that is already reeling from the outset of the crisis,” U.N. Secretary-General António Guterres said.

Russia, China and Pakistan proposed a draft resolution for the Council that calls for: an immediate and unconditional ceasefire; the protection of civilians; respect for international law and engaging in dialogue and negotiations.

China’s U.N. Ambassador Fu Cong said the country “strongly condemns the U.S. attacks on Iran” and blamed American officials for “exacerbated tensions in the Middle East.”

“The international community must uphold justice and make concrete efforts to cool down the situation and restore peace and stability,” Cong said.

Meanwhile, United Kingdom Ambassador to the U.N. Barbara Woodward said it has “long made clear” that Iran “cannot have a nuclear weapon as it represents a serious threat to peace and security.”

“The United States took action last night to alleviate that threat. The United Kingdom did not participate in U.S. or Israeli strikes, but military action alone cannot bring a durable solution to concerns about Iran’s nuclear program,” Woodward said. “My Prime Minister has been clear. We urge Iran now to show restraint, and we urge all parties to return to the negotiating table and find a diplomatic solution which stops further escalation and brings this crisis to an end.”

Acting U.S. Ambassador Dorothy Shear said the United States was acting in defense of Israel and American citizens, emphasizing the administration’s need to stop Iran from getting a nuclear weapon.

Israel and Iran’s remarks at the UN Security Council

Iran’s ambassador to the U.N., Amir-Saeid Iravani, told the United Nations that Iran reserves its “full and legitimate right under international law to defend itself against this blatant U.S. aggression.”

“The timing, nature and the scale of Iran’s proportionate response will be decided by its armed forces,” Iravani said.

Israel’s U.N. Ambassador, Danny Danon, said the United States’ action “was a necessity and righteous act for the United States, for Israel, for the Middle East and for the world.”

“So the entire world should say on record today, here and now, thank you,” Danon said.
