Families of Dallas police officers mourn their loss

Families of the five white police officers that were shot dead by a black man during a protest rally on Thursday, have began mourning their loss.

Two police cars outside Dallas Police Department and Dallas Area Rapid Transit have become growing memorials to those that lost their lives, covered with cards, flowers and balloons.

US President Barack Obama says the US is "not as divided as some have suggested" in the wake of fatal shootings involving African-Americans.
