A Hamas leader killed in Beirut. U.S. strikes in Baghdad. This week, tensions in the Middle East have been rising – and with them, the specter of a widening Israel-Gaza war. Our correspondent in Beirut joins us to explain what happened this week.Read more:On Tuesday, senior Hamas leader Saleh Arouri was killed in a suspected Israeli drone strike in a Beirut suburb called Dahieh. Hezbollah, an Iran-aligned Lebanese militant and political group, holds sway in the densely packed neighborhood.In an anxiously anticipated speech the next day, Hasan Nasrallah, the leader of Hezbollah, promised there would be a “response and punishment” to the assassination of Arouri and warned Israel against a wider war in Lebanon. Also on Wednesday, at least 95 people were killed in two blasts that struck the central Iranian city of Kerman, where thousands of mourners had gathered to commemorate Maj. Gen. Qasem Soleimani on the fourth anniversary of his assassination in a U.S. drone strike in 2020. The Islamic State has since taken credit for the blasts. Then on Thursday, the U.S. killed an Iran-linked militia commander with an airstrike Baghdad.All of these attacks have raised questions about the conflict in Gaza expanding into the kind of wider war that Israel, Iran and its allies have so far avoided.
