Hundreds of people in Beirut fled their homes as about a dozen explosions were heard across the Lebanese capital on Sunday evening, shortly after Israel announced it would aim at sites linked to the financial operations of Lebanon’s Hezbollah group.

At least 12 strikes were reported Saturday in Beirut in the heaviest attack Lebanon's capital saw in more than a week.

Israel’s military announced it will now take aim at Lebanon-based Hezbollah’s financial arm and plans to attack a “large number of targets” in the coming hours in Beirut and elsewhere. Explosions began in Beirut’s southern suburbs about an hour later on Sunday.

Explosions have been heard in Beirut after Israel warned it would target Hezbollah's financial arm. Hundreds have evacuated their homes. Sky News UK’s Alex Rossi says these attacks are an "escalation because this is civilian infrastructure”.
