U.S. officials said Israel launched a rare airstrike inside Syria on Wednesday. The target was a convoy believed to be carrying anti-aircraft weapons bound for Hezbollah, the powerful Lebanese militant group allied with Syria and Iran. The Israeli airstrike comes at a particularly sensitive and vulnerable time for Hezbollah in Lebanon. Despite its formidable weapons arsenal and political clout in the country, the group's credibility and maneuvering space has been significantly reduced in the past few years, largely because of the war in neighboring Syria but also because of unprecedented challenges at home.
