Britain, the United States and Canada are increasing travel curbs on members of the Iranian government over Iran's disputed nuclear programme, Britain's Foreign Office said in a statement.

'The UK is working closely with its partners to prevent a wide range of individuals connected with Iran's nuclear enrichment and weaponisation programmes from entering our countries,' Foreign Secretary William Hague said.

'These include scientists, engineers and those procuring components,' he added.

Hague said the measures were being coordinated with partners such as the United States and Canada.-Reuters
