Trump says we're 'blowing up the whole country' if Iran doesn't make deal in 48 hours

The second crew member aboard the F-15E shot down over Iran on Friday has been rescued by U.S. military forces who conducted a rescue mission earlier on Saturday night, two U.S. officials confirmed to ABC News.

The crewmember who was rescued was the weapon systems officer aboard the two-seater aircraft that was downed by Iranian fire on Friday, according to another U.S. official.

The pilot of the F-15E was rescued on Friday by U.S. search and rescue personnel.

Two Black Hawk helicopters that were part of the mission also took Iranian fire as they attempted the rescue mission on Friday. There were injuries to some of the crewmembers, but they were able to return to safety.

An A-10 Warthog aircraft that was providing close air support to the rescue mission was also hit by Iranian fire, but managed to make its way back to Kuwait where the pilot ejected safely before the plane crashed.

President Donald Trump posted a video to social media on Saturday appearing to show what he called a "massive" strike on Tehran, Iran, with the president saying the attack terminated "Many of Iran's Military Leaders."

"Many of Iran's Military Leaders, who have led them poorly and unwisely, are terminated, along with much else, with this massive strike in Tehran!" Trump posted on social media along with the video.

Trump's post did not include any details about when the strikes happened or specific targets. ABC News has not independently verified the authenticity of the video.

The roughly minute-long video depicts a mostly dark view of what Trump said was Tehran, until a bright cloud appears with at least four explosions seconds apart.

This post comes as the president has not directly responded to Iran's attacks on U.S. aircraft on Friday.

The Israel Defense Forces on Saturday night issued an "urgent warning" to anyone in the crossing area of the Syrian-Lebanese border, saying the army "intends to launch airstrikes on the crossing in the near future."

"For your safety, we urge all those near the crossing and anyone in the area marked in red on the map to evacuate immediately," the IDF said in the notice.

The IDF claims that Hezbollah uses the crossing "for military purposes and for smuggling weapons."

Iranian merchants and trade groups are offering a reward of 10 billion tomans, about $60,000, for anyone who finds the "invading American pilot" from a warplane that crashed in Iran. Additional recognition has also been promised by authorities.

An Iranian official in Kohgiluyeh and Boyer Ahmad province, Iran, said a U.S. warplane has crashed in the area and that the pilot or pilots could be on the ground.

The provincial governor, Yadollah Rahmani, is calling on locals -- especially the tribal communities -- to report sightings and help detain them, saying capturing them alive is the priority.
