The British High Commission in the Fiji capital is to have an isolation zone built around it because of the fear of terrorist attacks.
Fiji TV reports that security barriers will be set up on the roads around the building to prevent the parking of vehicles that could be loaded with explosives for use as car bombs.
The measures follow last week's terrorist attack on the Australian embassy in Jakarta and increased risk at British diplomatic missions around the world.
The Suva City Council says it has approved the building of the security barrier because of the risk of possible terrorist action against the High Commission.
A similar barrier has been in place around the US embassy in Suva since its diplomatic missions were attacked in East Africa in the late 1990s causing hundreds of deaths.
