The sight of Christmas posters may have motivated Akayed Ullah's Nov. 11 bombing in New York City.
Ullah, 27, told investigators he meant to detonate his homemade pipe bomb in the busy subway station after seeing the walls plastered with Christmas posters, reports the Daily Mail.
A native of Bangladesh, Ullah told police that the Christmas-themed posters reminded him of ISIS's calls last month for militants and lone wolves to attack holiday markets.
His attack at the Port Authority Bus Terminal subway station occurred just days after President Donald Trump's controversial formal recognition of Jerusalem as Israel's capital -- a decision which sparked violence between Israelis and Palestinians in the Gaza Strip.
Two Palestinians were killed in an alleged assassination by an Israeli military drone, reports Haaretz.
While being treated at Bellevue Hospital for serious burns and lacerations, Ullah told investigators that his bombing attempt was in revenge for the Israeli attack.
Authorities say that if the explosive had fully detonated in the busy Midtown Manhattan subway station, there would have been more injuries and loss of life.
"This was an attempted terror attack and thank God the perpetrator did not achieve his ultimate goals," Mayor Bill de Blasio said.
New York Gov. Andrew Cuomo said that a successful subway bombing would be "one of our worst nightmares." He added: "We understand that anyone can go on the internet and download garbage and vileness on how to put together an amateur-level explosive device and that is the reality that we live with."
In a statement, Donald Trump blamed "lax" immigration policies for the attack, and urged Congress to "enact legislative reforms to protect the American people."
White House Press Secretary Sarah Huckabee Sanders reiterated that sentiment in a statement issued on behalf of the administration.
"This attack underscores the need for Congress to work with the president on immigration reforms that enhance our national security and public safety," she said. "We must protect our borders. We must ensure that individuals entering our country are not coming to do harm to our people and we must move to a merit-based system of immigration."
"The president is certainly concerned that Congress, particularly Democrats, have failed to take action in some places where we feel we could have prevented this," she added. "Specifically, the president's policy has called for an end to chain migration and if that had been in place, that would have prevented this individual from coming to the United States."
