Putin offers Iran mediation support as US negotiating team withdraws from failed Islamabad talks

**TL;DR**: The core claims are substantiated. Putin did call Iran's president offering mediation support after US-Iran talks collapsed in Islamabad, and the US delegation including top negotiators departed after marathon negotiations yielded no breakthrough.

**Claim 1**: Russian President Vladimir Putin called Iranian President Masoud Pezeshkian on Sunday to offer support in resolving the Middle East crisis following the collapse of Iran-US talks.

**Evidence**: The Kremlin released a readout confirming Putin held a phone conversation with Pezeshkian on Sunday. The statement emphasized Putin's "readiness to further facilitate the search for a political and diplomatic settlement to the conflict, and to mediate efforts to achieve a just and lasting peace in the Middle East." Multiple independent sources corroborated the call occurred following the collapse of Iran-US negotiations.

**Verdict**: TRUE

**Analysis**: The claim is fully corroborated. The Kremlin explicitly stated Putin offered to facilitate a political and diplomatic settlement and mediate for peace in the Middle East. The timing directly follows the collapse of US-Iran talks in Islamabad.

**Claim 2**: The entire US negotiating team withdrew from failed discussions in Islamabad, with no US officials remaining in Pakistan's capital to continue back-channel efforts.

**Evidence**: A US official travelling with Vice President JD Vance at Ramstein Air Base stated no members of the delegation stayed behind in Islamabad. The delegation, including chief negotiators Steve Witkoff and Jared Kushner, departed after marathon talks produced no significant breakthrough. Earlier speculation suggested further negotiations might continue, but the official confirmed the team fully withdrew.

**Verdict**: MOSTLY TRUE

**Analysis**: The core claim about the US delegation leaving is confirmed. The specific detail about zero officials remaining is supported by the US official's statement that no team members stayed behind. However, the evidence does not definitively rule out other US officials who may have been in Pakistan independently.

**Claim 3**: US chief negotiators Steve Witkoff and Jared Kushner departed after marathon talks in Islamabad yielded no meaningful progress on the Iran conflict.

**Evidence**: Multiple sources confirm Witkoff and Kushner were the chief negotiators representing the US in Islamabad. Reports indicate the talks lasted 21 hours in private sessions. Vice President JD Vance stated at Ramstein Air Base that "we need to see an affirmative commitment that they will not seek a nuclear weapon," signaling no breakthrough was achieved. Iran's parliament speaker Mohammad Bagher Ghalibaf said Washington failed to build trust during the discussions.

**Verdict**: MOSTLY TRUE

**Analysis**: The claim is substantially accurate. Both Witkoff and Kushner were confirmed as chief negotiators, the talks were marathon at 21 hours, and no meaningful progress occurred. The US side's post-talk statements and Iran's characterization confirm the negotiations failed to produce any breakthrough.
