New York and Washington stepped up security in the wake of the attacks in Brussels on March 22, deploying counterterrorism reinforcements and the National Guard to airports and stations, officials said. The NYPD said there was no indication that the attacks in Belgium were connected to New York but ordered the steps as America's biggest city of 8.4 million began the morning commute. About 35 people were killed and more than 200 wounded on Tuesday in bombings at the Brussels airport and a metro station in the city that is home to the European Union and NATO.
