Iran has struck a border target and escalated warnings to Washington amid renewed tensions.

• An explosion struck near a police headquarters in Zahedan, days after the Revolutionary Guard said it eliminated a group of cells.
• The Revolutionary Guard struck sites it said belong to armed Kurdish opposition along Iran's border with Iraqi Kurdistan.
• Iran's government said Foreign Minister Abbas Araghchi received the US response to its proposal via Qatar, with talks focused on the Strait of Hormuz.
• Parliamentary National Security Committee head Ebrahim Azizi threatened to target remaining US military presence in the region if Iran's security is threatened.
• Iran and the US exchanged written proposals for the first time in a month and a half, disagreeing over sequencing, the Strait of Hormuz and the nuclear file.
• Araghchi presented the official US response to President Masoud Pezeshkian at a cabinet meeting on Wednesday, without disclosing its contents.
• His proposal offered to reopen the Strait of Hormuz within a week in exchange for lifting the blockade on Iranian ports and releasing frozen assets.
• The Revolutionary Guard said Thursday it dismantled a "terrorist cell" in the Manzel Ab area of Zahedan, killing six members.
• The IRGC's Quds Headquarters said the operation was based on local reports and intelligence monitoring.
