British woman killed in Tunis attack: Foreign minister

LONDON (AFP) - A British tourist was among those killed in the attack on a museum in Tunis, Prime Minister David Cameron said Thursday, vowing that Britain would not "let terrorists undermine democracy".

"We will do everything we can to help the family of the British woman murdered in Tunisia. We will not let terrorists undermine democracy," he said in a tweet.

The tourist, named as Sally Adey, was on an excursion to the National Bardo Museum with her husband at the time. He survived the attack, British officials said.

"The Tunisian people are rightly proud of their democratic transition," foreign minister Philip Hammond said in a separate statement, condemning a "despicable act".

"Cowardly attacks, such as the one we saw yesterday, must not be allowed to undermine what they have achieved," he said.
