The U.N. Security Council scheduled an emergency meeting Thursday to discuss Iran's deadly protests at the request of the United States, even as President Donald Trump left unclear what actions he would take against the Islamic state.

Tehran appeared to make conciliatory statements in an effort to defuse the situation after Trump threatened to take action to stop further killing of protesters, including the execution of anyone detained in Tehran’s bloody crackdown on nationwide protests.

The U.N. Security Council scheduled an emergency meeting on Iran for Thursday afternoon at the request of the United States.

Iran closed its airspace to commercial flights for hours without explanation early Thursday and some personnel at a key U.S. military base in Qatar were advised to evacuate. The U.S. Embassy in Kuwait also ordered its personnel to “temporary halt” travel to the multiple military bases in the small Gulf Arab country.

Iran previously closed its airspace during the 12-day war against Israel in June.

Iran's crackdown on the demonstrations has killed at least 2,615, the U.S.-based Human Rights Activists News Agency reported. The death toll exceeds any other round of protest or unrest in Iran in decades and recalls the chaos surrounding the country’s 1979 Islamic Revolution.

Lufthansa halts night flights to and from Tel Aviv and Amman

Europe’s largest airline group said Thursday it would halt night flights to and from Tel Aviv and Jordan's capital Amman for five days, citing security concerns as fears grow that unrest in Iran could spiral into wider regional violence.

Lufthansa — which operates Swiss, Austrian Airlines, Brussels Airlines and Eurowings — said flights would run only during daytime hours from Thursday through Monday “due to the current situation in the Middle East.” It said the change would ensure its staff — which includes unionized cabin crews and pilots -- would not be required to stay overnight in the region.

The airline group also said its planes would bypass Iranian and Iraqi airspace, key corridors for air travel between the Middle East and Asia.

Iran closed its airspace to commercial flights for several hours early Thursday without explanation.

A spokesperson for Israel’s Airport Authority, which oversees Tel Aviv’s Ben Gurion Airport, said the airport was operating as usual.

State media denies man arrested during recent protests was condemned to death

Iranian state media has denied claims that a young man arrested during Iran’s recent protests was condemned to death. The statement from Iran’s judicial authorities on Thursday contradicted what it said were “opposition media abroad” which claimed the young man had been quickly sentenced to death during a violent crackdown on anti-government protests in the country.

State television didn’t immediately give any details beyond his name, Erfan Soltani. Iranian judicial authorities said Soltani was being held in a detention facility outside of the capital. Alongside other protesters, he has been accused of “propaganda activities against the regime,” state media said.

New Zealand says it is ‘appalled’ with Iran situation

New Zealand’s Foreign Minister Winston Peters said Thursday that his government was “appalled by the escalation of violence and repression” in Iran.

“We condemn the brutal crackdown being carried out by Iran’s security forces, including the killing of protesters,” Peters posted on X.

“Iranians have the right to peaceful protest, freedom of expression, and access to information – and that right is currently being brutally repressed,” he said.

Peters said his government had expressed serious concerns to the Iranian Embassy in Wellington.
