An editorial from the UK's Independent on why the recent terror alerts give the damaging impression Europe is somehow unsafe in general.
Last week's reports that terror attacks are being planned in Europe on the model of the atrocities committed in Mumbai in 2008 have prompted action from the US authorities.
The State Department yesterday issued a "travel alert" to all US citizens planning to visit Europe, warning them to be vigilant.
And the UK's Foreign Office followed soon after, suggesting that there was a "high threat" of an attack on the continent.
The intelligence reports which prompted these alerts should be taken seriously. It is clear that European cities are potentially vulnerable to the sort of commando-style suicide raid that took place in India's commercial hub two years ago. The death toll from the Mumbai attacks (which left around 173 dead) was fearful, especially considering the relatively small number of terrorists involved.
