Three people were killed when devices exploded in Bekaa in eastern Lebanon, Lebanon's NNA news agency reported on Wednesday.
Earlier in the day, a Lebanese source told Sputnik that communication devices other than pagers had exploded in different parts of Lebanon.
"Communication devices used by Hezbollah members exploded in different parts of Lebanon, different from the pagers that detonated less than 24 hours ago," the source said.
More than 20 people injured as a result of detonation of communication devices in several Lebanese neighborhoods, Qatar's Al Jazeera broadcaster reported.
Al Hadath TV channel in turn reported that at least 100 people were injured in new explosions of communication devices in Lebanon.
Videos of fires in homes and cars in the southern suburbs of Beirut and in a number of settlements in southern Lebanon have appeared on social media. It is reported that the fires were caused by explosions of communication devices.
Local media report that walkie-talkies detonated in Lebanon on Wednesday were purchased by the Hezbollah movement around the same time as the pagers - about five months ago.
On Tuesday, pagers detonated in different parts of Lebanon. According to a number of media reports, pagers are used by members of the Hezbollah movement as a closed communication system, the least susceptible to hacking and wiretapping. Lebanese Health Minister Firass Abiad said that some 2,700-2,800 people were injured by the detonation of pagers.
