Local media in Lebanon reported on Tuesday a major security incident in the south of the capital Beirut in the Dahieh district. 

Dozens of people have been injured across Lebanon after explosions occurred in pager devices they were carrying, caused by an Israeli breach into the devices.

Preliminary unconfirmed reports say that dozens were injured in Dahieh. 

A communication device is said to have exploded in the Beirut suburb, injuring several members of Hezbollah.

Meanwhile, Hezbollah's Al Manar has reported that "Wireless communication devices (Pagers) explode, injuring their users in a number of Lebanese areas."

In the meantime, Al Jazeera has reported that the communications device that is being used by the Lebanese Resistance group has been penetrated, hacked and a number of Hezbollah members have been  injured after these devices, which are known as pagers, exploded.

Hezbollah Secretary General Hassan Nasrallah was not harmed in the spree of pager blasts across Lebanon, a senior Hezbollah told Reuters.
