Pakistan announces US-Iran talks 'in coming days'

Iran's parliament speaker, Mohammad Bagher Qalibaf, said in a post to X on Wednesday that Tehran is "closely monitoring all U.S. movements in the region, especially troop deployments."

"What the generals have broke, the soldiers can't fix; instead, they will fall victim to [Israeli Prime Minister Benjamin] Netanyahu's delusions," Qalibaf added.

"Do not test our resolve to defend our land," Qalibaf -- who is widely considered one of the most influential officials within the Iranian regime -- wrote.

Qalibaf's warning came amid the expected U.S. deployment of thousands of Marines and Army servicemembers to the Middle East.

The Israel Defense Forces said Wednesday that it struck two sites in Tehran that it alleged were used to produce naval cruise missiles.

The sites were used for "developing and producing long-range sea cruise missiles that enable rapid destruction of targets at sea and on land," the IDF said.

The Trump administration sent a 15-point plan to end the war to Iran that was delivered via Pakistan, two sources familiar with the plan tell ABC News.

The sources said the plan addresses Iran's ballistic missile and nuclear programs as well as maritime routes, but would not provide any other details -- including which Iranian officials were sent the proposal. It is also unclear whether Israel has signed onto the proposal.

Iran continues to insist that no negotiations are underway.

The New York Times was the first to report the proposal.

White House press secretary Karoline Leavitt said in a statement, "As President Trump and his negotiators explore this newfound possibility of diplomacy, Operation Epic Fury continues unabated to achieve the military objectives laid out by the commander in chief and the Pentagon."

Fewer than 1,500 troops from the 82nd Airborne are set to deploy to the Middle East, according to a source familiar with the matter.

The source said the mobilization will include ground forces and a headquarters element, which oversees logistics and planning. The troops are expected to leave "soon," once they have received orders being developed Tuesday, the source said.

A brigade -- about 3,000 soldiers -- of the 82nd is constantly on standby as the Immediate Response Force, tasked to be able to deploy anywhere in the world within 18 hours.

The division specializes in seizing contested territory by parachuting out of airplanes. The 82nd is light infantry -- meaning they do not come with any tanks or other large vehicles.

The 82nd Airborne Division is based out of Ft. Bragg, North Carolina, and co-located with Pope Air Force Base.
