US President Donald Trump has signed an executive order introducing several police reforms while rejecting calls to defund or dismantle the police. His order offers federal grants to improve practices, including creating a database to trace abuses by officers.

It comes amid anger over the police killings of African Americans, though Trump did not comment about the ongoing US racism debate. Several US cities have proposed more radical reforms.

Speaking at the White House, Trump began by saying he had met a number of African-American families who had lost loved ones, including the relatives of Antwon Rose, Botham Jean and Ahmaud Arbery - the black jogger killed in Georgia earlier this year. No representatives of the families were present with the President, who spoke while flanked by law enforcement officers.
