US-brokered Russia-Ukraine peace talks resume in Abu Dhabi

US-brokered talks between Russia, Ukraine, and the U.S. begin Tuesday in Abu Dhabi, renewing efforts to negotiate a peace deal after a months-long pause. The two-day session focuses on security guarantees. Moscow and Kyiv remain far apart on key issues, including territorial control and Ukraine's NATO membership. Russia demands Ukraine withdraw from four annexed regions and drop its NATO bid, while Ukraine rejects ceding territory and insists on security guarantees to prevent future invasion. The U.S. says a broader European security agreement is being developed, with envoys meeting separately with European and NATO officials. Both sides have escalated aerial attacks, with Russia targeting Ukraine's power grid and Ukraine striking Russian oil refineries.
