Hezbollah has launched "phase one" of its attack on Israel with hundreds of rockets and drones overnight in retaliation for the assassination of a senior commander last month.
In response the Israel Defence Forces (IDF) hit back with air strikes inside Lebanon.
Hezbollah said they had completed "the first phase" of their offensive and their full response "would take some time".
The exchange of strikes is a major escalation in the Middle East amid fears of regional conflict.

The escalation between Israel and Hezbollah has triggered fears of a wider regional conflict - with the potential of involving both the United States and Iran.
US President Joe Biden is said to be following the events closely.
National Security Council spokesperson Sean Savett said: "At his direction, senior US officials have been communicating continuously with their Israeli counterparts.
"We will keep supporting Israel’s right to defend itself, and we will keep working for regional stability."
