At least thirty attacks were carried out during the night in Beirut, according to Lebanon's state news agency. Several powerful explosions were heard, according to AFP, which is on the scene. Among other things, a gas station is said to have been hit.
Twice during the night, Israel urged residents in targeted areas to evacuate before the attacks on marked buildings. Israel's military says it has carried out a series of attacks on several weapons installations and infrastructure.
TV footage shows a massive fireball over a residential area in southern Beirut, followed by a loud bang and further explosions. In the Sabra area near the southern suburbs, dozens of people fled, some on foot and others on motorcycles, from the intense bombing during the night.
Hezbollah has responded with rockets against Israel, fired from Lebanon. Israel's military says that three drones have also been stopped en route to targets in Israel. Meanwhile, ground battles are ongoing in the border areas with Israel.
Israel has also stepped up attacks on targets in Gaza on Sunday.
