The United States (U.S.) yesterday vowed to strengthen its effort to combat terrorism, saying extremist ideologies would not be allowed to flourish anywhere in the world.

The U.S. in a release on the commemoration of the 15th anniversary of September 11, 2001 terrorist attacks on World Trade Centre (WTC) in New York and the Pentagon which left thousands of people dead, said that countries of the world must stand together and work to defeat the scourge. It called for renewed commitment to fighting terrorism, as the activities of terrorists remain potential threats to freedom and world peace.

The statement from the U.S. Mission to Nigeria reads: “Tomorrow marks the 15th anniversary of one of the most tragic days in the history of the United States. Terrorists staged attacks on the WTC and the Pentagon. They were only prevented from completing another attack by the heroism of the passengers on board of United Flight 93. The images of that day are forever imprinted on our memories.

“The events of that day revealed the character of American citizens who demonstrated their courage and willingness to sacrifice for their fellow men and women.

“Sadly, tragic events throughout the world have shown the ongoing horrific impact of terrorism in Nigeria, Mali, Burkina Faso, France, Bangladesh, Turkey, and Belgium, among many other countries. Far too many families have experienced pain and loss as a result of terrorism. It is clear that we all must stand together and work to defeat this scourge.”

The U.S. said it would continue to remember the victims of the attack, calling for renewed international commitment to defeat terrorism across the globe.

The statement added: “We must defeat terrorists and all that they represent, and at the same time work tirelessly to promote dialogue, peace, and reconciliation in order to resolve the complex problems that we face in this interdependent world.”
