S Korea activists gather in protest at Jeju naval base

Demonstrators are gathering on the South Korean island of Jeju to protest at construction of a new naval base.

Tensions have been rising over the past week as police moved in to the site to remove protesters who have been blocking access since June.

The government says the $970m (£600m) development is vital for national security.
