World leaders united in outrage at Paris terror attacks

World leaders have expressed shock at the violence in Paris, which killed dozens of people Friday night.

German Chancellor Angela Merkel says she is “deeply shaken by the news and pictures that are reaching us from Paris.” The German leader issued a statement saying her thoughts were with the victims “of the apparent terrorist attack.”

The Secretary-General of the NATO alliance says he is “deeply shocked by horrific Paris attacks.” Jens Stoltenberg said in a Twitter message that “We stand together with the people of #France. Terrorism will never defeat democracy.”

U.N. Secretary-General Ban Ki-moon is condemning “the despicable terrorist attacks” in Paris and is demanding the immediate release of numerous hostages being held in the Bataclan theater.

President Barack Obama is calling the attacks on Paris “outrageous attempt to terrorize innocent civilians” and is vowing to do whatever it takes to help bring the perpetrators to justice.

Speaking to reporters at the White House, Obama said he would not speculate about who was responsible.

He called the attacks a “heartbreaking situation” and an “attack on all of humanity.”

Obama was briefed on the attacks Friday by his counterterrorism adviser Lisa Monaco.

The attacks come as the president is preparing for two trips abroad. He’s slated to leave Saturday for a nine-day trip to Turkey, the Philippines and Malaysia. He due to travel to Paris for climate change talks at the end of the month.

British Prime Minister David Cameron says he is “shocked” by the Paris attacks and violence.

Cameron said on Twitter “Our thoughts and prayers are with the French people. We will do whatever we can to help.”

New York City Mayor Bill de Blasio says New York is constantly on alert for coordinated terror attacks, especially in the wake of an attack in Paris that has killed dozens.

De Blasio said in an interview with WABC-TV on Friday the attack was not only sobering, but a reminder that police officials need to be prepared and vigilant for a possible follow-up attack.

Police have stressed there is "no indication that the attack has any nexus to New York City."

Officers have been deployed to various locations in the city, including French government buildings.
