NYC on alert after Soleimani's killing

In New York City, Mayor Bill de Blasio announced on Friday he was consulting with city officials about police steps to protect key locations “from any attempt by Iran or its terrorist allies to retaliate against America,” after the U.S. killing of top Iranian commander Qaseem Soleimani.

"We will have to be vigilant against this threat for a long time to come," said the mayor.

"No one has to be reminded that New York City is the number one terror target in the United States," De Blasio tweeted, "We're taking escalation in the Middle East seriously."

The City of New York Police Department (NYPD) will deploy additional, heavily armed officers at prominent sites around the city, officials said.
