As new US-led naval patrols in the Persian Gulf raise the stakes with Iran and Tehran’s nuclear deal collapses, the ongoing tensions have drawn renewed attention to foreign military bases in the region.

Here’s a look at the presence of the US and others in the region:

AFGHANISTAN:

The US has stationed some 14,000 troops in Afghanistan supporting America’s longest war. Some 8,000 others come from NATO forces.

BAHRAIN

The US Navy’s 5th Fleet, which oversees the region, is based in Bahrain, an island nation off the coast of Saudi Arabia that is home to over 7,000 American troops. Sheikh Isa Air Base on the island also hosts American fighter jets, surveillance aircraft and a US special forces operations center. The US considers the island a “major non-NATO ally.” Britain, meanwhile, has just opened its first military base east of the Suez Canal since 1971 in Bahrain.

IRAQ

The US has some 5,000 troops in Iraq in the aftermath of the war against the Islamic State group.

KUWAIT

The tiny, oil-rich nation hosts over 13,000 American troops and the US Army Central’s forward headquarters. It also maintains forces and equipment at two air bases and a naval base in the country. Kuwait International Airport also hosts the US military’s largest regional air logistics point. Some 2,200 American mine-resistant tactical vehicles are stationed there. The US also considers Kuwait a “major non-NATO ally.”

OMAN

A few hundred US military personnel are based in Oman. The sultanate also allows US military overflights and port visits. It also allows the US to preposition munitions in the country. America signed a new port access agreement with Oman this year. Britain has signed a deal to build a new naval base in the country.

QATAR

The forward headquarters of the US military’s Central Command is at Qatar’s sprawling Al Udeid Air Base, home to up to 13,000 American troops. Qatar plans to further expand the base, which saw the US position nuclear-capable B-52 bombers there as tensions rose with Iran. Turkey also has its own military base in the country, to the chagrin of Saudi Arabia, which sees Ankara as a regional rival for influence.

SAUDI ARABIA

The US pulled troops out of Saudi Arabia in the wake of the Sept. 11 terror attacks and the 2003 invasion of Iraq. Al-Qaida leader Osama bin Laden long criticized the presence of American forces there. This summer, US officials said fighter aircraft, air defense missiles and likely more than 500 American troops would return to Riyadh’s Prince Sultan Air Base over tensions with Iran. US special operations troops also reportedly have assisted Saudi forces along its border with war-torn Yemen.

UNITED ARAB EMIRATES

Dubai’s Jebel Ali port in the United Arab Emirates is the largest port of call for the US Navy outside of America. The UAE hosts 5,000 US military personnel, many at Abu Dhabi’s Al Dhafra Air Base, where American drones and advanced F-35 jetfighters are stationed. The US Navy also maintains a small base in Fujairah on the Gulf of Oman. France also maintains its own navy base in Abu Dhabi, the Emirati capital.
