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."

White House press secretary Karoline Leavitt said on Sunday that the Iran war would, for now, remain an air campaign, adding that President Donald Trump has not removed sending in ground troops from his table of options.

"It has been, and it will continue to be,” Leavitt said Sunday morning on Fox about the current U.S. military operations, which have largely been an air campaign.

“And President Trump wisely does not remove options off the table," Leavitt said. "I know a lot of politicians like to do that quickly, but the president, as commander-in-chief, wants to continue to assess the success of this military operation. It's not part of the current plan right now, but the president, again, wisely keeps his options on the table."

Leavitt was also asked about how the conflict in the Middle East is impacting the economy, and how that might influence the hotly-contested midterm elections in November.

Leavitt said Trump can "walk and chew gum at the same time" by handling conflicts abroad and tackling domestic issues related to the economy.
