US President Donald Trump and Ukrainian leader Volodymyr Zelensky have discussed efforts to revive peace talks with Russia and a deal to allow Ukraine to make Patriot missile interceptors. Mr Zelensky held a private meeting with Mr Trump in the Oval Office, in the absence of reporters, before the funeral of US senator Lindsey Graham in the afternoon. The visit offered Mr Zelensky an opportunity to shore up military support at a moment when US-Ukraine relations are warmer than they have been in months. “We talked with the president about licences for producing interceptors for the Patriots and other ideas that could help,” Mr Zelensky said, without providing further details. Ahead of the Oval Office meeting, a White House official said Mr Trump would discuss the peace process between Russia and Ukraine with the Ukrainian president.
