倫敦襲擊後英國領導人態度堅定

British Prime Minister Theresa May struck a defiant tone after an attacker killed four people and injured about 40 others near Britain's Parliament in London, saying people should go about their business as usual Thursday.

"They will board their trains, they will leave their hotels, they will walk these streets, they will live their lives and we will all move forward together, never giving in to terror and never allowing the voices of hate and evil to drive us apart," May said.

The prime minister added that lawmakers would hold their normal meeting Thursday.

But London is under extra security with a boost in both armed and unarmed officers as police continue to investigate the attack that began Wednesday with a car running into pedestrians on Westminster Bridge.

Mark Rowley, head of counterterrorism efforts for London's Metropolitan Police Service, said authorities believe they know the attacker's identity, but are not yet releasing that information.

"We have hundreds of officers on this investigation and they are focusing on the suspect's motivation, preparation and his associates," Rowley told reporters.

He said authorities are working on the assumption that the attack was an act of "Islamist-related terrorism."

Rowley also identified the security officer who died in the attack as 48-year-old Keith Palmer, a husband and father who had served in British law enforcement for 15 years.

Prime Minister May addressed the public on television, calling the attack "sick and depraved."

May said any attempt to intimidate the British people through violence and terror is doomed to failure.英國首相特蕾莎·梅在倫敦的英國議會附近發生襲擊後態度堅定，鼓勵人們星期四像往常一樣活動。這次襲擊造成4人死亡，大約40人受傷。

梅首相說，“他們會搭上火車，會離開他們的酒店，會走過這些街道，會過着他們的生活，我們都會一起前進，永遠不要被恐怖嚇倒，永遠不要讓仇恨的聲音來驅使我們。”

梅補充說，議會議員們星期四將照常舉行會議。

不過，隨着警方繼續調查從星期三在威斯敏斯特大橋上開車撞人開始的襲擊事件，倫敦增加了武裝和非武裝的警力，加強安全戒備。

倫敦大都會警察局的反恐工作負責人馬克·羅利表示，當局相信他們已經確認襲擊者的身份，但尚未發佈這一信息。

羅利對記者說：“我們有數以百計的調查人員調查此案，他們的重點是嫌疑人的動機、準備工作和他的同夥。”

他說，有關當局的工作是基於這次襲擊是一次“與伊斯蘭分子有關的恐怖行動”。

羅利確認，48歲的保安人員基思·帕爾默在襲擊事件中遇難。他家有妻小，在英國執法機構供職15年。

英國首相梅週三早些時候在電視上對公衆發表了講話，稱這次襲擊是“病態和邪惡”的。

梅首相說，任何企圖通過暴力和恐怖恐嚇英國人的企圖都註定要失敗。
