The Israeli embassy in Washington, D.C. and the Israel Defense Forces both declined to comment.
A Lebanese television network owned by Hezbollah, an Iran-backed movement, said “pager devices are exploding in the hands of their carriers” across the country, and that the Lebanese health ministry had placed hospitals on high alert.
Emergency rooms in Lebanon were overwhelmed with patients and requesting donations of blood, according to the AP.
The incident comes amid escalating tensions between Israel and Hezbollah. The two sides have repeatedly clashed since the Oct. 7 attack on Israel by Hamas, and Israel’s subsequent war in Gaza.
Iranian state media said Mojtaba Amani, Tehran’s ambassador to Lebanon, was among those injured.
“The U.S. was not involved,” White House Press Secretary Karine Jean-Pierre said Tuesday. “The U.S. was not aware of this incident of the hundreds of pagers that were going to explode in Lebanon ahead of time.”
