Early Friday morning, a bomb was detonated on the London Underground, injuring 29 people and stopping all movement in the Tube. Officials quickly launched a search for the terrorist in the city of London.

Officials say that the explosive was a homemade bucket bomb. Detectives from the London Metropolitan Police Counter Terrorism Command arrested an 18-year-old man Saturday morning in the port area of Dover and a 21-year-old man late Saturday in West London.

According to the New York Times, “The bomb, wrapped in a plastic grocery bag concealed in a bucket, exploded at 8:20 a.m.”

The police have not released any details on the men arrested and their possible connections to the attack. Officials have hinted that there may be more people involved.

Other terrorist attacks in England within the last year include the June 3 London Bridge attack by an Islamic terrorist. On June 19, only 16 days later, a man in a van drove into a group of people near a mosque in Finsbury Park, killing one person and injuring 10. A month before these attacks, on May 22, a suicide bomber killed 22 people and injured 59 people following an Ariana Grande concert in the city of Manchester. Islamic Briton Salman was identified as the bomber in the attack. Two months earlier on March 22, five people were killed by Khalid Masood, who drove a rented car into pedestrians on Westminster Bridge before stabbing a police officer to death outside the British Parliament.

Despite the fact that the bomb was detonated on a crowded subway train, no one was killed. Ambulance services said that none of the injuries were serious or life threatening, and the majority of the injuries were merely flash burns. Since there were no deaths and two suspects have been taken into custody, the terror threat in the United Kingdom has been lowered from “critical” to “severe.”

England is beginning to pay much more attention to these attacks and has invested $32.6 million in counter terrorism around the country in an attempt to prevent future attacks.

Mt. Hebron senior Kevin Wang said, “I think the attack is horrible. However, I’m so immune to these attacks out of the United States that it really did not affect me in any way.”

He went on to explain, “Hurricane Harvey was destroying Houston around the same time, so I was more worried about that than the attack in London.”

In 2017, there have been 979 terrorist attacks with a total of 5,668 fatalities around the globe. Other attacks around Europe have included the August 17 attack in Barcelona, Spain, killing 16 people and injuring 136 others. In Paris, France, there have been seven terrorist attacks this year, but only one person has been killed.

The biggest terrorist attacks around the world include Kabul, Afghanistan on May 31, where a car bombing killed more than 150 people and injured around 413 people. In Libya on May 20, a shooting killed 141 people and injured 100 others.

According to UK news source The Daily Mirror, terror attacks are increasing by 25% each year. With a great rise in terrorist attacks around the world and more people being killed every year, terrorist organizations are starting to become one of the top global dangers around the world.
