Iran’s ambassador to Beirut was wounded in a pager explosion Tuesday but his injuries were not critical, state media reported.

“Iranian ambassador to Lebanon Mojtaba Amani was injured in a pager explosion,” state television said, adding that he was “conscious and in no danger.”

More than 1,000 people, including Hezbollah fighters and medics, were wounded on Tuesday when the pagers they use to communicate exploded across Lebanon, security sources told Reuters.

A Hezbollah official, speaking on condition of anonymity, said the detonation of the pagers was the “biggest security breach” the group had been subjected to in nearly a year of war with Israel.

Israel and the Iran-backed Hezbollah have been engaged in cross-border warfare since the Gaza war erupted last October, the worst such escalation in years.

The Israeli military has not commented on the detonations.
