WASHINGTON: The United States and Iran are set for talks this weekend in Oman as President Donald Trump reiterated this week threats of military action against Tehran if it does not agree to limits on its nuclear program.
Western countries suspect Iran is pursuing nuclear weapons, which Iran denies.
If Iran does not make a deal, Trump has said, “There will be bombing, and it will be bombing the likes of which they have never seen before.”
Here is what we know about the US military presence in the Middle East:

WHERE ARE US BASES IN THE MIDDLE EAST?
The US has operated bases around the Middle East for decades and the largest is Al Udeid Air Base in Qatar, built in 1996, based on the number of personnel.
Other countries where the US has troops include Bahrain, Kuwait, Saudi Arabia and the United Arab Emirates.
There are normally about 30,000 US troops across the region, down sharply from when US forces were involved in major operations. There were more than 100,000 US troops in Afghanistan in 2011 and over 160,000 in Iraq in 2007.
The US has roughly 2,000 troops in Syria at small bases mostly in the northeast. About 2,500 US personnel are stationed in Iraq including at the US Union III site in Baghdad.

WHAT REINFORCEMENTS HAS TRUMP SENT?
The Pentagon has said that it surged additional forces to the Middle East in recent weeks.
It also relocated as many as six B-2 bombers in March to a US-British military base on the Indian Ocean island of Diego Garcia, which experts said would put them in an ideal position to intervene quickly in the Middle East.
US Defense Secretary Pete Hegseth has said that it was up to Iran to decide whether to interpret this as a message to Tehran.
The Pentagon has also sent other aircraft and more air defense assets including a Patriot missile defense battalion.
Two US aircraft carrier ships are in the Middle East, and each carries thousands of troops and dozens of aircraft.

WHY ARE US TROOPS STATIONED IN THE REGION?
US troops are stationed in the Middle East for a variety of reasons.
In some countries like Iraq, US troops are fighting Daesh militants and local forces. But over the past several years Iran-backed fighters have attacked US personnel who have struck back.
Jordan, a key US ally in the region, has hundreds of US trainers and they hold extensive exercises throughout the year.
US troops are in other countries such as Qatar and the UAE as a security assurance, for training and to assist in regional military action as needed.
The United States is undertaking a bombing campaign against Iran-backed Houthi forces in Yemen.
DO US BASES IN THE REGION GET ATTACKED OFTEN?
US bases are highly guarded facilities, including air defense systems to protect against missiles or drones. Facilities in countries like Qatar, Bahrain, Saudi Arabia, Kuwait are not usually attacked.
But US troops in Iraq and Syria have come under frequent attack in recent years.
Since 2023, the Houthi movement has launched more than 100 attacks on ships off Yemen’s coast, which they say were in solidarity with Palestinians over Israel’s war in Gaza with Iran-backed Hamas militants.
These include drone and missile strikes on US Navy ships in the region. So far, no Houthi attack is known to have damaged a US warship.

TEL AVIV, Israel: Israel’s military said Friday it will fire air force reservists who signed an open letter that condemns the war in Gaza for mainly serving political interests while failing to bring home the hostages.
In a statement to The Associated Press, an army official said there was no room for any individual, including reservists on active duty, “to exploit their military status while simultaneously participating in the fighting,” calling the letter a breach of trust between commanders and subordinates.
The army said it had decided that any active reservist who signed the letter will not be able to continue serving. It did not specify how many people that included or if the firings had begun.
Nearly 1,000 Israeli Air Force reservists and retirees signed the letter, published in Israeli media Thursday, demanding the immediate return of the hostages, even at the cost of ending the fighting.
The letter comes as Israel has ramped up its offensive in Gaza, trying to increase pressure on Hamas to return the 59 hostages still being held. More than half are presumed dead. Israel has imposed a blockade on food, fuel and humanitarian aid that has left civilians facing acute shortages as supplies dwindle. It has pledged to seize large parts of the Palestinian territory and establish a new security corridor through it.
While those who signed the letter did not refuse military service, they are the latest in a growing number of Israeli soldiers speaking out against the prolonged conflict, some saying they saw or did things that crossed ethical lines.
“It’s completely illogical and irresponsible on behalf of the Israeli policy makers … risking the lives of the hostages, risking the lives of more soldiers and risking lives of many, many more innocent Palestinians, while it had a very clear alternative,” Guy Poran, a retired Israeli Air Force pilot who spearheaded the letter told The AP.
He said he’s not aware of anyone who signed the letter being fired, and since it was published, it has gained dozens more signatures.
Israel’s Prime Minister Benjamin Netanyahu downplayed the letter on Friday, saying it was written by a “small handful of weeds, operated by foreign-funded (non-governmental organizations) whose sole goal is to overthrow the right-wing government.” He said anyone who encourages refusal will be immediately dismissed.
Soldiers are required to steer clear of politics, and they rarely speak out against the army. After Hamas stormed into Israel on Oct. 7, 2023, Israel quickly united behind the war launched against the militant group. Divisions here have grown as the war progresses, but most criticism has focused on the mounting number of soldiers killed and the failure to bring home hostages, not actions in Gaza.
Advocates for hostage return keep up the pressure
Freed hostages and their families are doing what they can to keep attention on their plight and urge the government to get everyone out.
Agam Berger, a military spotter who was taken hostage and freed in January, plans to join an upcoming March of the Living Ceremony at the sites of former Nazi concentration camps in Poland. Berger, playing a 130-year-old violin that survived the Holocaust, will be accompanied by Daniel Weiss, a resident of Kibbutz Be’eri whose parents were killed by Hamas.
But the war ignited by that attack shows no signs of slowing.
Since Israel ended an eight-week ceasefire last month, it said it will push farther into Gaza until Hamas releases the hostages. More than 1,000 people have been killed in Gaza since the ceasefire collapsed, according to the United Nations.
The Israeli military on Friday issued an urgent warning to residents in several neighborhoods in northern Gaza, calling on them to evacuate immediately. At least 26 people have been killed and more than 100 others wounded in the last 24 hours, according to Gaza’s Health Ministry, which doesn’t distinguish between civilians and combatants.
Palestinians lined up at a charity kitchen Friday in central Gaza said shortages of food, fuel and other essentials are worsening.
“There is no flour or gas or wood. Everything is expensive and there is no money,” said Reem Oweis, a displaced woman from Al-Mughraqa in south Gaza, waiting in line for a serving of rice, the only food available.
“I completely rely on charity kitchens. If those charity kitchens close, my children and I will die,” said another displaced woman, Nema Faragallah.
Brazil pushes for the release of body of teen who died in Israeli custody
Also this week, Brazil’s Embassy in the West Bank said it had requested the immediate release of the body of a 17-year-old Palestinian prisoner who died in Israeli custody.
A representative from Brazil’s office in Ramallah, told the AP it was helping the family speed up the process to bring Walid Ahmad’s body home. Ahmad had a Brazilian passport.
According to an Israeli doctor who observed the autopsy, starvation was likely the primary cause of his death.
Ahmad had been held for six months without being charged. He was extremely malnourished and also showed signs of inflammation of the colon and scabies, said a report written by Dr. Daniel Solomon, who watched the autopsy conducted by Israeli experts at the request of the boy’s family.
Israel’s prison service said it operates according to the law and all prisoners are given basic rights.
