The United States Treasury Department announced new sanctions on Iran Monday, targeting three individuals and one entity involved in nuclear research. Secretary of State Marco Rubio stated that these sanctions address activities that contribute to the proliferation of weapons of mass destruction.

Rubio emphasized that all sanctioned parties are engaged in efforts that materially support Iran’s expanding nuclear program. “The United States' actions are intended to delay and degrade the ability of SPND [Iran's Organization of Defensive Innovation and Research] to conduct nuclear weapons research and development,” he said.

These sanctions are the latest step in Washington's efforts to curb Iran’s nuclear ambitions. The targeted individuals and entities are accused of facilitating research and development activities that pose a direct threat to global security.

The announcement comes as the United States and Iran engage in indirect negotiations over Tehran's nuclear program. Iranian officials have characterized these discussions as “difficult but useful,” signaling ongoing challenges in reaching a diplomatic resolution.

Rubio’s remarks highlight the Biden administration’s continued commitment to preventing nuclear proliferation and maintaining international security. The sanctions reflect Washington’s strategy of applying economic and political pressure while pursuing diplomatic avenues.

As tensions persist, the international community closely watches the impact of these measures on Iran's nuclear trajectory and broader regional stability.
