Iran has been launching daily missile salvos at Israel for the past week since a wide-ranging Israeli attack on its nuclear and military facilities triggered war.

One projectile slammed into an area by the docks in Haifa on Friday afternoon where it damaged a building and blew out windows, littering the ground with rubble, AFP images showed.

Israel's foreign ministry said it struck "next to" the Al-Jarina mosque.

The locations of missile strikes in Israel are subject to strict military censorship rules and are not always provided in detail to the public.

A spokesman for Haifa's Rambam hospital said 19 people had been injured in the city, with one in a serious condition.

A military official said that "approximately 20 missiles were launched towards Israel" in the latest Iranian salvo.

More than 450 missiles have been fired at the country so far, along with about 400 drones, according to Israel's National Public Diplomacy Directorate.

The directorate added that the country's tax authority had received over 25,000 claims linked to damage caused to buildings during the war.

Israel launched a massive wave of strikes on June 13, triggering an immediate retaliation from Tehran.

Residential areas in both countries have suffered, while Israel and Iran have traded accusations of targeting civilians.

At least 25 people have been killed in Israel by Iranian missile strikes, according to authorities.

Iran said on Sunday that Israeli strikes had killed at least 224 people, including military commanders, nuclear scientists and civilians. It has not updated the toll since.
