Lebanon's Health Ministry said that nine people were killed and 300 wounded in a new wave of device explosions.
The latest detonations were heard across Beirut's southern suburbs, which is a stronghold of the Hezbollah militant group.
"The new wave of walkie-talkie explosions... killed nine people and wounded more than 300," the ministry said in a statement.
It comes a day after another wave of blasts on Tuesday, which Hezbollah and the Lebanese government blamed on Israel. Israel has not commented on the incident.
The first round of explosions killed at least 12 people and wounded nearly 3,000.
Company linked to Hezbollah pagers has no production in Hungary, government says
A company linked to pagers that exploded while being used by Hezbollah members in Lebanon has "no manufacturing" site in Hungary, a government spokesman said.
"Authorities have confirmed that the company in question is a trading intermediary, with no manufacturing or operational site in Hungary... The referenced devices have never been in Hungary," government spokesman Zoltan Kovacs said on X.
He also added that Hungarian national security services are cooperating with all relevant international partner agencies and organizations and that the case "poses no national security risk" to Hungary.
Gold Apollo, a Taiwanese company initially thought to have made the devices, earlier said that the Hungary-based firm BAC, which has a license to use the Gold Apollo brand and design, had actually manufactured the pagers.
Hezbollah communication devices detonate across southern Lebanon
Communications equipment used by Lebanon's Shiite Hezbollah group exploded late Wednesday afternoon in the south of the country and in the southern suburbs of the capital, Beirut, the AFP and Reuters news agencies said, citing their sources and a witness.
According to the sources, the devices were not pagers but walkie-talkies, the hand-held radios.
At least one of the blasts occurred during a funeral organized by Hezbollah for those killed a day earlier when thousands of pagers used by the group exploded across the country.
Lebanon's Health Ministry said one person has been killed and more than 100 injured by exploding electronic devices in several regions of the country.
Meanwhile, the state-run Lebanese News Agency (NNA) said at least three people were killed in the blasts in the western Bekaa Valley.
