Obama: Gunmen cruel, calculating and despicable

President Obama has condemned the attack on police officers in Dallas sharply from Warsaw.

'I speak for all Americans when I say that we are shocked by the events,' he said at a press conference in Poland where he is attending a NATO summit. He said that he has conveyed his condolences to the mayor of Dallas.

'There is no justification for violence against the police,' said Obama, who again turned his sights on the gun laws in his country. 'We know that walking around as people with heavier weapons, these kinds of shootings deadly and tragic. '
