President Joe Biden is “deeply concerned” about the unauthorized release of classified documents on Israel's preparation for a potential retaliatory attack on Iran, a White House spokesman said Monday.

President Joe Biden is "deeply concerned" about a leak of classified documents that contain the US's assessment of Israeli plans to attack Iran, White House National Security Council spokesman John Kirby said. Officials have not determined whether the documents were released due to a hack or a leak, Mr Kirby said.

The Israeli military has carried out a wave of airstrikes targeting branches of a financial institution affiliated with Lebanon’s Hezbollah, saying the quasi-banking system is being used to fund the militant group’s military wing.

The strikes targeted Al-Qard Al-Hassan branches in the southern neighborhoods of Beirut, across southern Lebanon and in the eastern Bekaa Valley.

After eliminating senior military leaders and weapons, Israel is hitting the group’s finances and role in serving Shiites.
