Iran backs any decision taken by Lebanon in talks to secure a cease-fire with Israel, a senior Iranian official said on November 15, signaling Tehran wants to see an end to a conflict that has dealt heavy blows to its Lebanese ally Hezbollah, which is designated a terrorist organization by the United States and whose military wing is blacklisted by the European Union. Israel launched air strikes in the Hezbollah-controlled southern suburbs of Beirut, flattening buildings for a fourth consecutive day. Israel has stepped up its bombardment of the area this week, an escalation that has coincided with signs of movement in U.S.-led diplomacy toward a cease-fire. Senior Iranian official Ali Larijani, asked whether he had come to Beirut to undermine the U.S. truce plan, said: "We are not looking to sabotage anything. We are after a solution to the problems."
