A US court has ordered Samsung to pay Apple $1.05bn (£665m) in damages after upholding allegations that several Samsung devices had infringed Apple's intellectual property, including design patents and some functionality.

Samsung has promised to appeal against the decision describing it as "a loss for the American consumer".
