Carmaker Toyota has announced its biggest recall, saying it will call in 3.8 million vehicles in the US.

The problem is with loose floormats, which may cause the accelerator pedal to stick.

The problem affects eight models of Toyota and Lexus cars and trucks in the US, where owners have been told to remove floormats on the driver's side.

The US government said it had received reports of 100 related incidents that involved 17 crashes and five deaths.
