Good morning on this soggy Tuesday, and Happy Hanukkah.
A would-be suicide bomber detonated a homemade explosive in a busy subway corridor near the Port Authority during yesterday’s morning commute, in what officials are calling an act of terrorism — the second in New York City in six weeks. The explosion filled the corridor with smoke and sent commuters scrambling into the streets.
Here’s what we know about the attack as of this morning.
What happened? A man detonated a pipe bomb that was strapped to his body in a pedestrian passageway between the Times Square and Port Authority subway stations around 7:20 a.m. yesterday. Here are detailed maps of where the attack took place.
Was anyone killed? No, but three people sustained minor injuries. The attacker was the only one severely injured; he was taken into custody by the police shortly after the bombing and was transported to Bellevue Hospital, where he was treated for burns to his hands and abdomen.
Who was responsible? Officials identified the man they arrested as Akayed Ullah, 27, of Brooklyn. Mr. Ullah moved to the United States from Bangladesh in 2011 on a family immigrant visa. He often prayed at a local mosque, worked for a time driving for a car service, and was described as a “good guy” by a cabdriver who knew him. Here’s what we know about Mr. Ullah and his life in Brooklyn.
Why did he do it? Mr. Ullah told investigators he selected the subway location because of its Christmas-themed posters, and he said the attack was retaliation for United States airstrikes against Islamic State targets in Syria and elsewhere, according to law enforcement officials. He told investigators he was radicalized online and had made a number of international trips during the last five years.

The crude, homemade device was assembled by packing match heads into a pipe and was detonated with a broken Christmas tree light powered by a nine-volt battery, according to people with knowledge of the device. The attacker said he learned how to make the bomb online. Here’s why the bomb malfunctioned.
How did officials respond? At a news conference at the scene, Mayor Bill de Blasio said, “The terrorists are not going to win, we’re going to keep being New Yorkers.” Many New Yorkers seemed to acknowledge the sentiment: They met the news with a shrug and continued with their day. President Trump called for immigration reform and an end to what he called “chain migration”.
Will this affect my commute today? The attack shut down the Port Authority and snarled transit through the region yesterday, but you can expect a normal trip to work today. All subway stations are open and all trains are running, according to the Metropolitan Transportation Authority.
Here’s what else is happening:
Weather
Yuck.
Our sidewalks are looking wet, and possibly slushy, as rain is forecast throughout the morning.
While the rain should let up by noon, it could drizzle off and on all day. Grab an umbrella. And a scarf — the high is near 47.

And Finally...

Hanukkah begins tonight at sundown.
If you’re looking for a way to celebrate, you can attend menorah lightings at Grand Army Plaza in Brooklyn at 5:30 p.m., in Washington Market Park at 5:30 p.m., in Stuyvesant Town at 6:30 p.m., and on the Lower East Side at 6:30 p.m.
The idea of lighting large menorahs in public began in 1973, when the Rabbi Menachem Mendel Schneerson launched a Hanukkah campaign to promote service and share the story of the holiday.
In 1974, the first large public menorah, four feet tall and made out of wood, was lit by a rabbi in front of Independence Hall near the Liberty Bell in Pennsylvania.
Three years later, New York City’s first large public menorah was erected and lit up on 59th Street and Fifth Avenue in front of the Plaza hotel.
“The menorah stands as a symbol of freedom and delivers a timely and poignant message of strength and liberty, reminding us of the great miracle of Hanukkah,” said Rabbi Motti Seligson, a spokesman for Chabad-Lubavitch, the organization responsible for the celebration.
Today, 15,000 Chabad public menorahs are lit in more than 100 countries, Rabbi Seligson added.
The celebration on Fifth Avenue begins tonight at 5:30 p.m., when a 32-foot gold menorah will be lit with the help of a crane. The menorah will sparkle every night for the next eight days, and the nightly celebrations include music, singing and warm latkes.
