Ukrainian President Volodymyr Zelenskyy is due to address the UN General Assembly after meeting Donald Trump, who said he believed a peace agreement with Russia could be reached sooner than expected. Zelenskyy is expected to outline security and de-escalation proposals, while seeking to influence negotiations and secure guarantees that could make any ceasefire sustainable.

Ukraine is requesting additional Patriot air-defence systems, help protecting its energy infrastructure and food exports, and support for producing interceptors domestically. Kyiv wants Russia to stop attacks on energy facilities, critical infrastructure and exports, while Trump has urged Ukraine to halt strikes on Russian oil refineries and warned he could impose tariffs on buyers of Russian energy. The discussions are particularly urgent before winter, with UN investigators warning that attacks on the power grid could leave millions without electricity or heating.
