Israeli forces had been preparing the makeshift sites in western Iraq since late 2024, the US newspaper reported.

Israel built two covert military outposts in Iraq’s western desert in advance of the US-Israel war on Iran, The New York Times has reported.

The daily reported on Sunday that Iraqi officials had identified two covert Israeli-operated base in Iraq’s western desert, citing an Iraqi official and a lawmaker. It said Israeli forces had been preparing to build one of the makeshift sites since late 2024, citing a regional official.

Last week, The Wall Street Journal reported that one base was established shortly before the war began and operated with the knowledge of the United States. It said the installation housed Israeli special forces and served as a logistical hub for their air operations. It also reportedly included search-and-rescue capabilities for downed pilots.

According to the newspaper, Israeli forces launched attacks from the base against Iraqi units that came close to discovering the site in early March. Open-source analysts cited by the report identified the suspected location using satellite imagery near Iraq’s border with Saudi Arabia.

The reports have added to months of conflicting accounts over alleged Israeli activity inside Iraq. On Thursday, Lieutenant-General Qais al-Muhammadawi, Iraq’s deputy commander of joint operations, said authorities had received reports of “individuals or movement” in the Najaf desert near Karbala, about 100km (62 miles) southwest of Baghdad, according to the state-run Iraqi News Agency.

The WSJ also referenced comments made in March by Israel’s former air force chief, Major-General Tomer Bar, who said Israeli special forces had carried out “extraordinary” operations during the conflict with Iran, though he did not specify where.

Iraqi officials have publicly denied authorising any foreign military presence in the area. “There is no agreement or consent for any force to be present in this location,” al-Muhammadawi said last week, before the details of the alleged Israeli outpost were reported.

However, the WSJ report said Baghdad privately lodged a protest with Washington in late March over suspected covert military activity, calling it a violation of Iraqi sovereignty.

US officials quoted by the newspaper said Washington was not involved in the operation. On Sunday, a senior Iraqi security official again denied reports that Israel had established a military base in the desert, speaking to Turkiye’s Anadolu news agency.

On Tuesday, the commander of Iraq’s Karbala operations told Al Jazeera that an Israeli military group had been detected in the Najaf desert in March, although he said it had remained in the area for less than 48 hours.

The reports come as Iraq faces growing pressure amid escalating tensions between the US, Israel and Iran.

Washington has repeatedly urged Baghdad to curb the influence of Iran-backed armed groups operating in Iraq. In March, US forces carried out strikes against the Popular Mobilisation Forces after attacks on a US diplomatic and logistics facility near Baghdad airport.

Iran has also raised concerns over the allegations. Iranian Ministry of Foreign Affairs spokesperson Esmaeil Baghaei said on Monday that Tehran would raise the issue with Iraqi authorities. He accused Israel of seeking to destabilise the region.

“Israel’s behaviour in the region shows that they do not respect any limits or red lines,” Baghaei said.
