A near-total internet blackout in Iran entered its 10th day on Monday, with connectivity at about 1% of its normal level, according to NetBlocks, a web tracker.

"As regional hostilities intensify, some 90 million Iranians are silenced and cut off from the global internet under a state-imposed shutdown," the tracker said on social media on Monday.

The Israeli military said it would "operate with force" on Monday against what it described as Hezbollah-related targets in Beirut's southern suburbs, saying it was issuing a warning for residents in the area to evacuate.

"In the coming hours, the Israel Defense Forces will operate with force against the terrorist infrastructure of Al-Qard al-Hasan Association, which constitutes a central element in financing Hezbollah's terrorist activities and harms the Lebanese economy in service of Iranian interests," Avichay Adraee, a spokesperson for the Isreal Defense Forces, said in Arabic on social media.

Iran on Monday launched missiles toward Israel, which the country’s defenses were working to intercept, the Israel Defense Forces said.

"The IDF has identified that missiles were launched from Iran toward the territory of the State of Israel a short while ago," the IDF said. "Defense systems are operating to intercept the threat."

Iranian missiles and drones were targeting the United Arab Emirates on Monday, the country’s Ministry of Defense said.

"UAE air defences are currently responding to incoming missile and drone threats from Iran," the ministry said on social media. "MOD asserts that the sounds heard are the result of the Air Defence."

As the Iranians get closer to naming their next supreme leader, President Donald Trump said Sunday the new leader "is not going to last long" if the Iranians don't get his approval first.

"He’s going to have to get approval from us," Trump told ABC News' chief White House correspondent Mary Bruce. "If he doesn’t get approval from us, he’s not going to last long. We want to make sure that we don’t have to go back every 10 years, when you don’t have a president like me that’s not going to do it."

The president added, "I don’t want people to have to go back in five years and have to do the same thing again, or worse, let them have a nuclear weapon," he said.
