The war entered its fourth week on Saturday.
President Donald Trump announced "major combat operations" against Iran on Feb. 28, with massive joint U.S.-Israel strikes attack targeting military and government sites, officials said.
Ayatollah Ali Khamenei was among those killed in Tehran on the first day of strikes and his son Mojtaba Khamenei was chosen to succeed him. Iran is responding with missile and drone attacks targeting Israel, regional U.S. bases and multiple Gulf nations. Iran is also attempting to block some shipping traffic through the Strait of Hormuz.
Israel is also intensifying its long-running strike campaign against the Iran-backed Hezbollah militia in Lebanon.

An Iranian drone struck the Mina Al-Ahmadi Refinery in Kuwait on Thursday, resulting in a "limited" fire at the facility, according to the official Kuwait News Agency.
No injuries were reported, the news agency said, citing a statement from the Kuwait National Petroleum Company, which runs the facility.
The near-total internet blackout in Iran entered its 20th day on Thursday morning, according to NetBlocks, an internet monitor.
"The incident is now the longest recorded shutdown in Iran's history, surpassing the blackout imposed during protests in January," NetBlocks said on social media.
A vessel was struck by an "unknown" projectile about 4 nautical miles east off the coast of Ras Laffan, Qatar, the U.K. Maritime Trade Operations Center said in a warning posted early on Thursday.
"All crew are reported safe and well," according to the UKMTO, a marine monitoring organization that works with merchant shipping and military forces in the region.
Iran on Wednesday had launched retaliatory strikes that included the targeting of a liquified natural gas terminal in Ras Laffan, an industrial hub on the Persian Gulf.
The UKMTO warning, which was tagged as "suspicious activity," came several hours after the UKMTO said another vessel was similarly struck about 11 nautical miles east of Khawr Fakken, the United Arab Emirates, causing a fire onboard.
The UKMTO did not publish details about either of the ships struck overnight. It was not immediately clear what type of projectile had struck either vessel.
"Since the start of the hostilities on 28 February, more than twenty incidents involving commercial vessels and offshore infrastructure have been reported across the Arabian Gulf, Strait of Hormuz, and Gulf of Oman," the UKMTO said in an advisory note published on Wednesday.
As the U.S. and Israel have struck Iran this month, Tehran has vowed to close the Strait of Hormuz, a vital shipping channel off its southern coast, to most ships. Iranian officials have claimed to have launched attacks on several ships traveling in or near the strait.
"The incidents involve a wide range of vessel types and flag states, with no consistent pattern of Western ownership linkage," the UKMTO said on Wednesday, "suggesting that the current strike patter reflects a campaign aimed at broad maritime disruption rather than selective vessel targeting."
