Pro-Palestinian activists hoping to breach the naval blockade of Gaza have run into trouble off the coast of Libya.

Their boat has reportedly been surrounded by Libyan warships following a row over payment.

The group, from the organisation Road to Hope, set sail earlier today from the Libyan port of Derna.

On board are seven British activists including two who were involved in the Mavi Marmara flotilla clashes in May.

A Foreign Office spokesman said they were working with the Libyan authorities to resolve the situation.
