The Israel Defense Forces said Saturday it had "completed a broad wave of strikes" overnight across Iran's capital and on military infrastructure located at Tehran's Mehrabad Airport.
"'Mehrabad Airport' was used by the Quds Force of the IRGC and served as a central hub for arming and funding the regime’s terrorist proxies in the Middle East. Aircraft loaded with weapons and cash took off from the airport numerous times and landed across the region for the use of the Iranian terror regime’s proxies," the IDF claimed in a statement.
"The strike on the military infrastructure at the airport not only disrupts the regime’s ability to arm Iran, but also terror proxies throughout the Middle East," the IDF claimed.
