A man in Florida with a lengthy criminal record was arrested and charged Friday with sending 13 packages containing improvised explosive devices to high-profile figures across the country, authorities said.

President Donald Trump late Saturday night criticized the FBI for failing to act on a tip that might have prevented the recent massacre at a high school in Parkland, Florida, and said the bureau was devoting too much time to its investigation of his presidential campaign.

FBI investigators failed to act on a warning that 19-year-old Nikolas Cruz might attack a school, ignoring a concerned call the bureau received just weeks before Cruz allegedly carried out a shooting rampage at a high school in South Florida on Valentine's Day, the FBI said Friday.

Federal authorities on Wednesday charged the 29-year-old Uzbek immigrant they say plowed a rented truck into people walking and cycling on a New York City bike path - killing eight - with providing support to a terrorist organization, alleging that he was inspired by the Islamic State to inflict mayhem and chose Halloween because he figured there w...

The girlfriend of Stephen Paddock, the gunman who opened fire on a country music festival in Las Vegas earlier this week, said Wednesday that she had no warning about his plans to carry out the massacre.

Investigators trying to determine what sparked the deadliest mass shooting in modern U.S. history have found the massacre to be the work of a sophisticated planner with the means and desire to inflict unprecedented carnage.

Perched in his suite at a high-rise hotel overlooking the Vegas Strip, a 64-year-old retiree with no real criminal history and no known affiliations with terror groups rained bullets down into a crowd at a country music festival Sunday, killing at least 59 people and injuring hundreds more in the deadliest mass shooting in modern American history.

President Donald Trump fired Acting Attorney General Sally Yates Monday night, after Yates ordered Justice Department lawyers Monday not to defend his immigration order temporarily banning entry into the United States for citizens of seven Muslim-majority countries and refugees from around the world.

An Ohio State student drove a car into a crowd outside a classroom building Monday morning, then got out and slashed at people with a butcher knife, sending 11 people to the hospital in what authorities said was a planned assault.

Surveillance footage from inside the Orlando club the night of the rampage shows Omar Mateen firing at people, stopping and then shooting again those who were already wounded, said officials who have viewed the evidence.

A little more than a week after the shooting rampage at Pulse, an Orlando nightclub, key details remain unknown about what exactly happened during the violent episode and the hostage standoff that followed.

On the day of his rampage at a gay nightclub, the Orlando shooter posted messages on Facebook pledging allegiance to the leader of the Islamic State and vowing that there would be more attacks in the coming days by the group in the United States, according to a letter sent to Facebook on Wednesday by Sen. Ron Johnson, R-Wisconsin, chairman of the S...

Omar Mateen had boasted to co-workers about his connections to al-Qaeda and dying as a martyr.

FBI Director James Comey suggested Thursday that the bureau paid more than $1 million to access an iPhone belonging to one of the San Bernardino attackers, the first time the agency has offered a possible price tag in the high-profile case.
