Iranian strikes on military bases used by the US in the Middle East caused about $800 million (£600 million) in damage in the first two weeks of the war, a new analysis shows.

Much of the damage was caused in initial retaliatory strikes by Iran in the week after the US and Israel launched the war, according to a report by the Center for Strategic & International Studies (CSIS) and an analysis by the BBC.

The full extent of the damage caused by Iranian strikes on US assets in the region is not clear. However, the $800 million in estimated damage to US military infrastructure - a figure that's higher than has been previously reported - offers a picture of the steep costs to the US as the conflict drags on.

Mark Cancian, a CSIS senior adviser and co-author of the think tank study, stated, The damage to US bases in the region has been underreported. Although that appears to be extensive, the full amount won't be known until more information is available.

In response to a request for comment, the US Department of Defense referred the BBC to US Central Command, which is leading the war. Officials there declined to comment.

Iran's retaliatory strikes targeted US air defense and satellite communication systems, among other assets, in Jordan, the United Arab Emirates and other countries across the Middle East. A significant portion of damage was caused by a strike on a US radar for a Thaad missile defense system at an air base in Jordan, which costs approximately $485 million.

Strikes by Iran caused an additional $310 million in estimated damage to buildings, facilities, and other infrastructure on US bases and military bases used by American forces in the region.

Analysis of satellite imagery indicated that Iran has struck at least three air bases multiple times, focusing on specific US assets. These bases include Ali Al-Salim in Kuwait, Al-Udeid in Qatar, and Prince Sultan in Saudi Arabia.

The US has also reported losses of 13 military service members since the start of the conflict, with civilian casualties estimated at around 1,400 according to Human Rights Activists News Agency.

The ongoing warfare has significant implications for the global economy, especially with disruptions in vital shipping routes like the Strait of Hormuz, prompting concerns about the extent of US military involvement in the conflict.
