The attack took place after a series of US media outlets reported on June 12 that US officials without names had revealed that Israel had completed all preparations to launch a military campaign against Iran. The scale and extent of the attack have not been made public, but all signs point to the approach of the arson.
Faced with the risk of the conflict spreading, Washington has given the green light to withdrawing unnecessary personnel from the embassy in Iraq, as well as allowing families of soldiers at bases in the Middle East to evacuate.
"Based on the latest situation analysis, we have decided to reduce our presence at the US mission in Iraq," the US State Department said on June 11 (local time). The withdrawals were also carried out at embassies in Kuwait and Bahrain.
The Pentagon has also approved the release of relatives of soldiers at regional military bases who volunteered to leave, amid growing concerns that the facilities could become targets of retaliation if Israel launched an attack.
It is unclear whether the US will directly participate in the Israeli operation. However, the sources said Washington could provide logistical assistance, share intelligence and be ready to protect Israel if Iran responds.
A US official affirmed that if Iran responded, the US would help Israel defend.
Escalating tensions between Israel and Iran arise as nuclear talks between the US and Tehran are at a standstill. Recent rounds of negotiations mediated by Oman have not achieved any breakthroughs.
President Donald Trump has said he is increasingly "unconfident" in the ability to reach a deal, while accusing Iran of deliberately "time-traveling" and not being good-natured.
Meanwhile, Iran insists it is ready for talks but is determined not to give up the right to enrich uranium, a key point that prompted the US to withdraw from the Iran nuclear deal in 2015.
Observers worry that the Middle East is approaching a new comprehensive military confrontation.
Many analysts warn that any military move could trigger a chain reaction from pro-Iran armed forces in the region, from Iraq, Syria to Lebanon - where Hezbollah is active.
