Nine people, including a child, have been killed after handheld pagers used by members of the armed group Hezbollah to communicate exploded across Lebanon, the country’s health minister says.

Iran’s ambassador to Lebanon was among 2,800 other people who were wounded by the simultaneous blasts in Beirut and several other regions.

Hezbollah, which is backed by Iran, said the pagers belonged “to employees of various Hezbollah units and institutions” and that at least two members were among the dead.
