Dallas shooting: Obama denies US polarised after deaths

President Obama says the US is not as polarised as some have suggested in the wake of fatal shootings involving the African-American community.

Five white police officers were shot dead during a protest rally in Dallas on Thursday.

The march was against the killing of black men by police. Two deaths this week have led to nationwide protests.

Mr Obama said "it was just not true" the US was returning "to the situation in the 60s".
