Several explosions have rocked Hezbollah strongholds in Lebanon, including the southern suburbs of Beirut, injuring at least 10 people, according to Lebanese security officials and Hezbollah's Al-Manar TV.

Investigation underway

The explosions, which occurred early on Friday, appear to have been caused by remote-controlled devices placed inside pagers, Al-Manar TV reported.

Hezbollah, a Lebanese Shia Islamist political party and militant group, has blamed Israel for the attack, which it called a "clear act of terrorism."

Israeli denies involvement

Israel has denied any involvement in the explosions.

Heightened tensions

The explosions come amid heightened tensions between Hezbollah and Israel, following a series of Israeli airstrikes on Hezbollah targets in Syria.

International condemnation

The international community has condemned the explosions, with the United Nations calling for a "thorough investigation" into the incident.

Call for calm

Lebanese President Michel Aoun has called for calm and urged all parties to avoid escalation.

Expert analysis

Impact on regional security

The explosions could also have a significant impact on regional security, as Hezbollah is a key player in the Middle East conflict.
