Three people were injured Monday when a man detonated an explosive in a Midtown Manhattan subway station. The suspect, identified as 27-year-old Akayed Ullah, was wearing "an improvised, low-tech explosive device" that he "intentionally detonated" around 7:20 a.m. ET Monday morning in the subway station below the Port Authority Bus Terminal, New York City Police Commissioner James O'Neill said.

Ullah, who is of Bangladeshi descent and lives in Brooklyn, was taken into custody after the blast. He sustained the most serious injuries, though he and the three injured passersby all escaped life-threatening harm. Ullah apparently told police he constructed the explosive at his workplace, while CNN reported, citing an unnamed law enforcement official, that Ullah may have been motivated to act by Israeli aggression.

In response to the attack, Attorney General Jeff Sessions blamed America's "failed immigration policies." He said in a statement that Monday's explosion, along with the truck-based attack in October near the Hudson River in Lower Manhattan, were due to policies that "do not serve the national interest," like "the diversity lottery and chain migration."

"It is a failure of logic and sound policy not to adopt a merit-based immigration system," Sessions said, adding that a merit-based policy would mean "welcoming the best and the brightest and turning away not only terrorists, but gang members, fraudsters, drunk drivers, and child abusers."
