Beirut: Hundreds of handheld pagers exploded near simultaneously across Lebanon and in parts of Syria on Tuesday, killing at least eight people, including members of the militant group Hezbollah and a girl, and wounding the Iranian ambassador, government and Hezbollah officials said.

Officials pointed the finger at Israel in what appeared to be a sophisticated, remote attack that wounded more than 2700 people at a time of rising tensions across the Lebanon border. The Israeli military declined to comment.

A Hezbollah official who spoke on condition of anonymity told The Associated Press that the new brand of handheld pagers used by the group first heated up, then exploded, killing at least two of its members and wounding others.

Lebanon’s health minister, Firas Abiad, said at least eight people were killed and 2750 wounded – 200 of them critically.

Iranian state-run IRNA news agency said that the country’s ambassador, Mojtaba Amani, was superficially wounded by an exploding pager and was being treated at a hospital.

Photos and videos from Beirut’s southern suburbs circulating on social media and in local media showed people lying on the pavement with wounds on their hands or near their pants pockets.

Hezbollah leader Hassan Nasrallah previously warned the group’s members not to carry cellphones, saying that they could be used by Israel to track their movements and to carry out targeted strikes.

Lebanon’s Health Ministry called on all hospitals to be on alert to take in emergency patients and for people who own pagers to get away from them. It also asked health workers to avoid using wireless devices.
