NZers warned over British terror threat

New Zealanders travelling to Britain are being warned to be extra vigilant after two failed car bombings in London and an attack on Glasgow Airport.

UK police said Friday's car bomb attempts and this morning's Glasgow attack - in which a burning jeep was driven into the airport terminal - were linked and being treated as terrorist incidents.

The UK Government placed Britain on "critical" alert after following the latest incident. The security rating is the Home Office's highest and indicates an attack is expected imminently.

On its website, the Ministry of Foreign Affairs and Trade (Mfat) said that New Zealanders in Britain should take account of the terror level threat when making travel decisions.

It said British authorities had put enhanced security measures in place, but advised New Zealanders to be careful.

"There is some risk to your security and New Zealanders are advised to maintain a high level of personal security at all times and to be extra vigilant when travelling on any public transport in the United Kingdom," it said.

Mfat also recommended New Zealanders in Britain monitor the media for information about possible new threats.
