BRITAIN UNDER ATTACK

 The brutal killing of a British soldier Wednesday near a military barracks in the Woolwich neighborhood of southeast London has shocked the United Kingdom, with Prime Minister David Cameron saying the act appears to be a terrorist attack.

Security was increased at army bases around London amid fears of additional attacks. The capital has not witnessed an alert of this kind since the summer of 2005, when London's public transport network was targeted with coordinated bomb attacks.

London's Metropolitan Police are not releasing the soldier's name per his family's wishes. Both men suspected in the attack were shot by police and are under guard at local hospitals. Authorities have not released their identities.
