Anti-racism protests continue in the US as statues, monuments and buildings of US historical leaders who carried out policies viewed as racist are being removed, following last month's police killing of unarmed black man George Floyd.
Nine members of one family were killed in the tragedy and an investigation has been launched, which will also bring the focus onto "duck boats". At least 40 people have been killed in the US in accidents involving the amphibious craft since 1999.
