Three people have been killed and hundreds injured in the latest spree of device explosions in Lebanon, Lebanon's state-run National News Agency (NNA) is reporting after a series of explosions appear to have hit multiple cities.

Hundreds of people were wounded in the blasts involving Hezbollah communication, a security source told Reuters.

Hezbollah’s walkie-talkies have been allegedly targeted in the widespread attack just one day after thousands of pager devices exploded.

Footage being shared on social media claims to show the moment that one of the walkie-talkies exploded during a funeral in the Beirut suburb of Dahiyeh. A man can be seen writhing on the floor moments after the blast, which impacted the funeral of four of the people killed in Tuesday's pager explosion.

A source in the terror group confirmed to the Guardian that Wednesday's explosions targeted the walk-talkie communication devices used by Hezbollah and the explosions were small, similar to Tuesday’s attack.

A security source told Reuters that handheld radios were bought five months ago by the terror group at the same time as the pagers were targeted.

Ambulances have been seen heading towards the suburbs of southern Beirut.

The incident comes a day after the attack against the terror group’s pagers, which injured over 2,800 people and killed 12.

Hezbollah blamed Israel for the attack on Tuesday and vowed revenge, but Jerusalem has yet to comment.
