Iran vowed retaliation and launched a wave of missile attacks on Israel Wednesday as it prepared to hold a funeral for security chief Ali Larijani, who was killed in an Israeli airstrike.

A barrage of Iranian missiles killed two people near Israel's commercial hub Tel Aviv, while Gulf nations intercepted rockets and drones headed for targets including U.S. bases in the region.

According to Iran's Fars and Tasnim news agencies, funerals for Larijani and another powerful figure killed by Israel, Gholamreza Soleimani, the head of the Basij paramilitary force, will take place from 10:30 a.m. GMT in Tehran.

Their deaths were announced on Tuesday.

Larijani is the most prominent figure of the Islamic Republic killed since Israel and the United States launched their attacks on Iran on Feb. 28, killing Supreme Leader Ayatollah Ali Khamenei and igniting a war across the Middle East.
