BEIRUT: A powerful Israeli airstrike targeted central Beirut on Saturday, security sources said, shaking the Lebanese capital as Israel pressed its offensive against Hezbollah.

At least four people were killed and 23 wounded in the attack in Beirut’s Basta neighbourhood, al-Manar broadcaster reported, citing the health ministry.

Lebanon’s National News Agency said early on Saturday that the attack resulted in a large number of fatalities and injuries and destroyed an eight-story building. Footage broadcast by Lebanon’s Al Jadeed station showed at least one destroyed building and several others badly damaged around it.

The blasts shook the capital around 4 a.m. (0200 GMT), Reuters witnesses said. Security sources said at least four bombs were dropped in the attack.

It marked the fourth Israeli airstrike this week targeting a central area of Beirut, where the bulk of Israel’s attacks have targeted the southern suburbs. On Sunday an Israeli airstrike killed a Hezbollah media official in the Ras al-Nabaa district of central Beirut.

Israel has killed several leaders of its long-time foe Hezbollah in air strikes on Beirut’s southern suburbs.

Israel launched a major offensive against Hezbollah in Lebanon in September, following nearly a year of cross-border hostilities ignited by the Gaza war, pounding wide areas of Lebanon with airstrikes and sending troops into the south.

A US mediator traveled to Lebanon and Israel this week in an effort to secure a ceasefire. The envoy, Amos Hochstein, indicated progress had been made after meetings in Beirut on Tuesday and Wednesday, before going to meet Israeli Prime Minister Benjamin Netanyahu and Defence Minister Israel Katz.
