WARSAW, Poland -- The White House says President Barack Obama will cut short his European trip and visit Dallas early next week, as the city mourns five police officers killed by a sniper.

Obama had been scheduled to return to Washington on Monday. Instead, he will leave Spain on Sunday night after a meeting with that country's interim prime minister and a visit with U.S. military personnel.

Obama is currently in Warsaw, Poland, for a NATO summit.

The White House says Obama will focus next week on efforts to support police officers while addressing "persistent racial disparities" in the criminal justice system.
