US being 'humiliated' by Iran, German chancellor says

The Trump administration is upping its efforts to target Iran's missile and drone program by slapping new sanctions on people and companies that it says are involved in supplying Iran with the key weapons.

The Treasury Department said it is “sanctioning 14 individuals, entities, and aircraft based in Iran, Türkiye, and the United Arab Emirates (UAE) for their involvement in procuring or transporting weapons or weapons components on behalf of the Iranian regime."

The administration’s targeting of Iranian weapons supplies comes as the U.S. has said that Iran's military capabilities have been severely diminished following Operation Epic Fury. This effort by the U.S. is to prevent Iran from rebuilding those military programs. The Treasury Department said in a statement that Iran is "seeking to reconstitute its production capacity" for drones and missiles.

"Iran is increasingly relying on Shahed-series one-way attack unmanned aerial vehicles (UAVs) to target the United States and its allies, including energy infrastructure in the region. These designations support Economic Fury in response to the Iranian regime’s continued threats to global security," the press release said.

The department said this new round of sanctions is authorized by a presidential memorandum signed by President Donald Trump last year, which aims to curtail Iran’s military and nuclear capabilities.

“The Iranian regime must be held accountable for its extortion of global energy markets and indiscriminate targeting of civilians with missiles and drones,” Treasury Secretary Scott Bessent said in a statement.

No final decision has been made on whether Iran will attend the Pakistan ceasefire talks, a spokesman for Iran’s Foreign Ministry, Esmaeil Baqaei, said on Tuesday.

"It is not due to indecision," he added, but rather due to "contradictory messages, inconsistent behavior, and unacceptable actions by the American side," he said in a phone interview on Iranian state TV.

"From the very outset, we have faced violations of the ceasefire by the opposing side, including measures such as a naval blockade," Baqaei said, adding that Iran will pursue a diplomatic track "whenever it determines that such a path serves its national interests."

Iran has not formally confirmed its participation in the Islamabad peace talks as of 10:30 a.m. ET, Pakistan's Minister of Information Attaullah Tarar said in a post on X on Tuesday.

With hours left before the U.S.-Iran ceasefire expires, Tarar said that Islamabad has made "sincere efforts" to convince the Iranian leadership to participate in the second round of talks, adding that these efforts continue.

"Decision from Iran to attend the talks before the end of two weeks ceasefire is critical," he wrote.

President Donald Trump projected confidence about the likelihood that a deal between the U.S. and Iran would be reached, saying that Iran has "no choice" but to send representatives, he said in an interview with CNBC.

"They have no choice but to send them. What I think is that we're going to end up with a great deal. I think it's got I think they have no choice," Trump said.

Trump added that he believes the U.S. is "in a very strong negotiating position" and doubled down on his insistence that the U.S. won't lift the blockade until after a deal has been reached.

"The blockade has been a tremendous success," Trump said.
