SANTA FE, N.M. (AP) — The Department of Defense is expanding a militarized zone along the southern U.S. border where troops are authorized to detain people who enter illegally for possible federal prosecution on charges of trespassing in a national defense area.
The Air Force announced Wednesday the annexation of a serpentine 250-mile (400-kilometer) stretch of the border in Texas amid a buildup of military forces under President Trump's declaration of a national emergency at the border. A Defense Department official said Thursday that the Navy also has been instructed to establish a new national defense area at the border. The official didn't provide further details.
The newly designated national defense area on land and water along the Rio Grande spans two Texas counties and runs alongside cities including Brownsville and McAllen. It will be treated as an extension of Joint Base San Antonio. The Air Force said it's prepared to install warning signs immediately against entry to the area.
The military strategy was pioneered in April along a 170-mile (275-kilometer) stretch of the border in New Mexico and expanded to a swath of western Texas in May. Hunters, hikers and humanitarian aid groups fear that they will no longer have access.
In the newest national defense area, military responsibilities include “enhanced detection and monitoring” and "temporarily detaining trespassers until they are transferred to the appropriate law enforcement authorities,” the Air Force said in a statement.
At least three people have been directly detained by troops in New Mexico for processing by Border Patrol. More than 1,400 immigrants have been charged with incursions into the national defense areas, a criminal misdemeanor punishable by up to 18 months in prison.
Court challenges to the charges have been met with mixed results.
The militarized border zone is a counterpoint to the deployment of roughly 4,000 National Guard troops and 700 Marines to Los Angeles following protests over Trump’s stepped-up enforcement of immigration laws.
The troop deployments are testing the limits of the Posse Comitatus Act, which prohibits the military from conducting civilian law enforcement on U.S. soil.
Arrests at the border for illegal entry have decreased dramatically this year.
This story has been corrected to show the Air Force announcement of a new national defense area was made Wednesday, not Monday.

DUBAI, United Arab Emirates (AP) — U.S. President Donald Trump said Iran wants to negotiate with Washington after his threat to strike the Islamic Republic over its bloody crackdown on protesters, a move coming as activists said Monday the death toll in the nationwide demonstrations rose to at least 544.
Iran had no immediate reaction to the news, which came after the foreign minister of Oman — long an interlocutor between Washington and Tehran — traveled to Iran this weekend. It also remains unclear just what Iran could promise, particularly as Trump has set strict demands over its nuclear program and its ballistic missile arsenal, which Tehran insists is crucial for its national defense.
Meanwhile Monday, Iran called for pro-government demonstrators to head to the streets in support of the theocracy, a show of force after days of protests directly challenging the rule of 86-year-old Supreme Leader Ayatollah Ali Khamenei. Iranian state television aired chants from the crowd, who shouted “Death to America!” and “Death to Israel!”
Trump and his national security team have been weighing a range of potential responses against Iran including cyberattacks and direct strikes by the U.S. or Israel, according to two people familiar with internal White House discussions who were not authorized to comment publicly and spoke on condition of anonymity.
“The military is looking at it, and we’re looking at some very strong options,” Trump told reporters on Air Force One on Sunday night. Asked about Iran’s threats of retaliation, he said: “If they do that, we will hit them at levels that they’ve never been hit before.”
Trump said that his administration was in talks to set up a meeting with Tehran, but cautioned that he may have to act first as reports of the death toll in Iran mount and the government continues to arrest protesters.
“I think they’re tired of being beat up by the United States,” Trump said. “Iran wants to negotiate.”
He added: “The meeting is being set up, but we may have to act because of what’s happening before the meeting. But a meeting is being set up. Iran called, they want to negotiate.”
Iran through country's parliamentary speaker warned Sunday that the U.S. military and Israel would be “legitimate targets” if America uses force to protect demonstrators.
More than 10,600 people also have been detained over the two weeks of protests, said the U.S.-based Human Rights Activists News Agency, which has been accurate in previous unrest in recent years and gave the death toll. It relies on supporters in Iran crosschecking information. It said 496 of the dead were protesters and 48 were with security forces.
With the internet down in Iran and phone lines cut off, gauging the demonstrations from abroad has grown more difficult. The Associated Press has been unable to independently assess the toll. Iran’s government has not offered overall casualty figures.
Those abroad fear the information blackout is emboldening hard-liners within Iran’s security services to launch a bloody crackdown. Protesters flooded the streets in the country’s capital and its second-largest city on Saturday night into Sunday morning. Online videos purported to show more demonstrations Sunday night into Monday, with a Tehran official acknowledging them in state media.
In Tehran, a witness told the AP that the streets of the capital empty at the sunset call to prayers each night. By the Isha, or nighttime prayer, the streets are deserted.
Part of that stems from the fear of getting caught in the crackdown. Police sent the public a text message that warned: “Given the presence of terrorist groups and armed individuals in some gatherings last night and their plans to cause death, and the firm decision to not tolerate any appeasement and to deal decisively with the rioters, families are strongly advised to take care of their youth and teenagers.”
Another text, which claimed to come from the intelligence arm of the paramilitary Revolutionary Guard, also directly warned people not to take part in demonstrations.
“Dear parents, in view of the enemy’s plan to increase the level of naked violence and the decision to kill people, ... refrain from being on the streets and gathering in places involved in violence, and inform your children about the consequences of cooperating with terrorist mercenaries, which is an example of treason against the country,” the text warned.
The witness spoke to the AP on condition of anonymity due to the ongoing crackdown.
The demonstrations began Dec. 28 over the collapse of the Iranian rial currency, which trades at over 1.4 million to $1, as the country’s economy is squeezed by international sanctions in part levied over its nuclear program. The protests intensified and grew into calls directly challenging Iran’s theocracy.
