- Authorities in New York charged Akayed Ullah, 27, with terror and weapons charges in the wake of Monday's attack. Federal officials on Tuesday charged Ullah with using a weapon of mass destruction.
Officers found Ullah with burns and cuts to his body on Monday morning after responding to a report of an explosion around 7:20 a.m. Authorities said Ullah had an explosive device strapped on when it detonated in an underground terminal near Times Square. He was taken into custody.
Although police said he intended to detonate the device, which they identified as a pipe bomb, investigators believe it went off earlier than planned.
- Dec 12, 2017 3:12 PM EST: Officials said Ullah entered the U.S. on an immigrant visa that was granted based on the fact that he had an uncle in the country.
Francis Cissna, director of U.S. Citizenship and Immigration Services, told reporters at a news briefing that Ullah's uncle came to the country years earlier as part of the visa lottery program. The program, established in 1990, grants visas to 50,000 people per year based on a lottery. Eligible people came from countries with low immigration rates in recent years.
- Dec 12, 2017 1:22 PM EST: Acting U.S. Attorney Joon H. Kim told The Associated Press that Ullah will have a hospital court proceeding on Tuesday or Wednesday after federal and local officials filed numerous charges against the 27-year-old.
Officials said they believe Ullah started planning the Manhattan attack two to three weeks ago, and that he built the pipe bomb that detonated Monday a week ago.
- Dec 12, 2017 11:36 AM EST: In documents filed in federal court Tuesday, officials said Ullah's radicalization began in 2014, after he watched pro-Islamic State videos, "including a video instructing, in substance, that if supporters of ISIS were unable to travel overseas to join ISIS, they should carry out attacks in their homelands."
"He began researching how to build IEDs on the Internet approximately one year ago," investigators said.
- Dec 12, 2017 11:22 AM EST: Before Ullah attempted to carry out a suicide bomb attack in New York City on Monday morning, he posted a message to President Donald Trump on Facebook, according to a criminal complaint filed Tuesday in federal court.
"Trump you failed to protect your nation," the post said, according to WNBC.
Authorities also found handwritten notations in a passport that bore Ullah's name, court records showed. One of the messages said, "O America, die in your rage."
- Dec 12, 2017 11:06 AM EST: Federal authorities on Tuesday charged Ullah with using of a weapon of mass destruction one day after officials said the 27-year-old attempted to carry out a suicide attack in New York City, WABC reported. He also faces charges of providing material support to terrorists and bombing of a public place, The Associated Press and WNBC reported.
- Dec 12, 2017 9:47 AM EST: Authorities did not have Ullah on their radar before Monday, when police said he detonated a bomb in an underground pathway near Times Square in New York City, injuring three people.
Neither New York police nor FBI officials were aware of Ullah, New York police Deputy Commissioner for Counterterrorism and Intelligence John Miller said Tuesday during an appearance on "CBS This Morning."
He says it's getting harder and harder to defend against such acts because would-be terrorists are going online to read propaganda without speaking with any larger group.
"He's somewhat characteristic of what we've been seeing across the world, which is somebody who turns up one day out of the blue," Miller said.

- The family of alleged New York bombing suspect Akayed Ullah released a statement through the Council on American-Islamic Relations, saying they are "heartbroken and deeply saddened by the suffering the attack has caused," according to the AP.
