Bob Marley's family is to sue Universal Music Group and US mobile phone firm Verizon Wireless in a row over ringtones featuring his music.

The family claims the firms have used the late star's name, likeness and image without permission.
However, Universal says it has not yet received any legal suit and dismissed the claims as "meritless".
It said the ringtones offer was within the terms of a long-standing contract between Bob Marley and UMG.
The offer, announced on Tuesday, said Verizon Wireless customers would be able to purchase ringtones of some of Marley's music exclusively on its service.
But Fifty Six Hope Road Music Ltd, which is owned by the Marley family, said it had not given permission for the tie-up between the two firms.
Universal Music Group, the world largest music company, owns Island Records, the label through which Marley recorded most of his global hits, such as One Love and I Shot The Sheriff.
His greatest hits compilation, Legend, is the biggest-selling reggae album of all time.
