Dozens of people were wounded in Beirut's suburbs after their handheld pagers exploded Tuesday, Lebanese state media and security officials said.

A senior military intelligence official and an official with a Lebanese group with knowledge of the situation, both of whom spoke on condition of anonymity because of the sensitivity of the situation said that pagers carried by Hezbollah members were detonated. The second official said it was believed to be an Israeli attack.

The state-run National News Agency reported that in Beirut's southern suburbs and other areas “the handheld pagers system was detonated using advanced technology, and dozens of injuries were reported.” It wasn't immediately clear if people were killed.

The Associated Press reached out to the Israeli military and they declined to comment.

The incident comes at a time of heightened tensions between Lebanon and Israel. The Lebanese militant group Hezbollah and Israeli forces have been clashing near-daily for more than 11 months against the backdrop of war between Israel and Hezbollah ally Hamas in Gaza.

The clashes have killed hundreds in Lebanon and dozens in Israel and displaced tens of thousands on both sides of the border.

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.
