The US government has intensified its efforts against Iran by announcing new sanctions targeting the Iranian oil network and several entities linked to its petroleum trade. This comes shortly after nuclear discussions in Oman, which ended without a consensus. President Trump has threatened tariffs of up to 25% on countries trading with Iran, signaling a tough stance on international commerce involving the nation. The latest sanctions include penalties on 15 entities and 14 vessels accused of facilitating Iranian oil transfers. These actions reflect ongoing tensions as Iran continues its nuclear enrichment activities, leading to stark warnings from US officials regarding potential consequences for nations engaging in trade with Tehran.
