Complaints lodged by Israel with committee overseeing its cease-fire with Lebanon allege the militant group is being propped up by the infusion of U.S. currency.

Israel has complained to the U.S.-led ceasefire committee that "Iranian diplomats and others are delivering tens of millions of dollars in cash to Hezbollah to fund the group’s revival," The Wall Street Journal quoted sources as saying.

The Israeli military said on Friday it struck several Hezbollah targets overnight in the Bekaa Valley and along the Syrian-Lebanese border.
