Iran launched multiple waves of missile against Israel during the 12-day war that began on 13 June when Israeli airstrikes hit Iranian nuclear and military sites and killed several IRGC top commanders.
Iranian strikes frequently targeted major cities including Tel Aviv and Haifa, as well as military areas around Beersheba.
Several residential buildings were also hit, though the Israeli military said most of the missiles and drones were intercepted.
Iran and Israel agreed to a US-backed ceasefire on June 24 after the United States bombed the Islamic Republic's nuclear facilities.
The British daily Telegraph reported on Monday that Iranian missiles struck five Israeli military facilities, citing satellite radar data reviewed by US researchers.
The data, provided by a research group at Oregon State University, suggest that six Iranian missiles hit military targets across northern, central, and southern Israel, including what the report describes as a major air base, an intelligence facility, and a logistics center.
A more comprehensive analysis of the damage to both Israeli and Iranian infrastructure is expected from the Oregon State research group within two weeks, according to the report.
