Where Is Queen Elizabeth? London Terror Attack Postpones British Monarch's New Scotland Yard Visit

Queen Elizabeth II and the Duke of Edinburgh postponed their visit to New Scotland Yard, following the terror attack on Westminster Bridge on Wednesday. The British monarch was scheduled to open the new Metropolitan Police Headquarters on Victoria Embankment near the place of the attack Thursday.

Four people, including the attacker, were killed during the attack that took place near the U.K. parliament. Buckingham Palace told the Royal Central that the monarch's visit will be rescheduled.

The Buckingham Palace spokesman said: "In light of today's events the decision has been taken to postpone The Queen's engagement to New Scotland Yard tomorrow. The visit will be rearranged for a later date."

According to the Royal Central, the monarch's trip was canceled because of mainly two reasons that included the safety and security of the queen and also because of the close distance between the Palace of Westminster and Scotland Yard. During the attack, the queen was at her residence at the Buckingham Palace. The armed police, patrolling along the premises of the royal residence, were forced to close the gates. After the incident, the public were told that several unarmed and armed police will be deployed on the streets of London.

Prime Minister Theresa May said the capital city would try to be as normal as possible in the face of terror. She said, "We will all move forward together, never giving in to terror and never allowing the voices of hate and evil to drive us apart." She also praised the "exceptional bravery" of the police while tackling the attack.

London Mayor Sadiq Khan issued a statement Wednesday, in which he offered his condolences to the families of victims and paid respect to the police officer who was killed. "Today London suffered a horrific attack near Parliament Square which we are treating as a terrorist attack. A number of people have lost their lives and at least twenty people have been injured. My heart goes out to those who have lost loved ones and to everyone who has been affected," he said.

"London is the greatest city in the world and we stand together in the face of those who seek to harm us and destroy our way of life. We always have, and we always will. Londoners will never be cowed by terrorism," Khan added.
