WARSAW, Poland -- President Barack Obama says America is "horrified" over the shootings of police officers in Dallas and there's no possible justification for the attacks.
Obama spoke from Warsaw, Poland, where he's meeting with leaders of the European Union and attending a NATO summit.
Obama says justice will be done and he's asking all Americans to pray for the fallen officers and their families. He also says the nation should express its gratitude to those serving in law enforcement.
Snipers opened fire on police officers in the heart of Dallas Thursday evening, killing five officers and injuring six others during protests over two recent fatal police shootings of black men. It marked the deadliest attack on law enforcement since the terrorist attacks of Sept. 11, 2001.
Obama said earlier there was no contradiction between supporting law enforcement and making certain biases in the justice system are rooted out.
