Gen. Abbas Nilforushan, a prominent general in Iran's Revolutionary Guard, was killed in an Israeli airstrike in Beirut. The killing adds pressure on Iran to respond as tensions rise in the Israel-Hamas war. Nilforushan served as the deputy commander for operations in the Guard and was a critic of Israel. Iran has signaled its desire to negotiate with the West over sanctions, but the death of Nilforushan may complicate those efforts.
