DUBAI (Reuters) -With ally Hamas under attack in Gaza, the head of Iran's Quds Force visited Beirut in February to discuss the risk posed if Israel next aims at Lebanon's Hezbollah, an offensive that could severely hurt Tehran's main regional partner, seven sources said. In Beirut, Quds chief Esmail Qaani met Hezbollah leader Sayyed Hassan Nasrallah, the sources said, for at least the third time since Hamas' deadly Oct. 7 attacks on southern Israel and Israel's devastating retaliatory assault on Gaza.
