Police have detained a person of interest in connection with a US shooting at Brown University that left two people dead and nine others injured.
An earlier order for people on the Brown campus and surrounding areas to shelter in place has also been lifted.
The attack on the campus brings the number of mass shootings in the US to 389 for this year, according to the independent analysis website Gun Violence Archive.
It defines mass shootings as having four or more victims killed or injured, not including the attacker.
Here’s what we know:
What happened?
The gunman opened fire in a classroom at around 16:00 local time (21:00 GMT) on Saturday at the Holley engineering building at the eastern end of Brown’s campus, according to officials.
Final exams were taking place in the building at the time of the shooting, the school said.
The Barus and Holley engineering building is a seven-storey block that includes 117 laboratories, dozens of classrooms and three lecture halls.
An economics professor told local public media outlet Ocean State Radio that the shooting had taken place during a review session for her course, which was led by her teaching assistant.
“He said that the shooter came in the doors, yelled something – he couldn’t remember what he yelled – and started shooting,” Rachel Friedberg said.
“Students started to scramble to try to get away from the shooter, trying to get lower down in the stadium seating, and people got shot,” she added.
On Saturday, investigators said they were not immediately sure how the shooter got inside the first-floor classroom.
Outer doors of the building were unlocked but rooms being used for final exams required badge access, Mayor of Providence Brett Smiley said.
Two students, who were studying in the nearby Rockefeller library when the active gunman alert came through, told the BBC they “stayed away from the windows” as they awaited a police escort.
Officers searched the floor, made them drop their bags and raise their hands before before being led out of the library, the pair said.
Brown University, one of the oldest higher education institutions in the US, is part of the Ivy League, a group of elite universities in the northeast of the country.
The university, which has more than 11,000 students, is in Providence, Rhode Island’s capital city, which is located about 50 miles (80km) from Boston and 180 miles (290km) from New York City.
Who are the victims?
Two students were killed in the incident and nine others were injured.
Smiley told reporters on Sunday that one person is in a critical condition and seven others are in a stable condition in hospital. One person with less severe injuries was discharged, he added.
The identities of those killed or injured have not yet been released, but Brown University President Christina Paxson told reporters in a press briefing that all the victims, including those killed and wounded, were students.
“This is a day that we hoped never would come to our community. It is deeply devastating for all of us,” she said in a statement.
In a statement on Sunday, the university said that the families of the two students killed were being supported.
“There are not enough words of comfort for families who lose a child, but we will do all we can,” Ms Paxson said.
According to police, a ninth victim did not suffer a gunshot wound, but had non-life threatening injuries from fragments from a shooting “that had occurred near them”.
Who is the gunman?
A person of interest was taken into custody in connection with the shooting, officials said on Sunday.
Providence Police Chief Oscar Perez said limited details would be released on the detained suspect, but said he was in his 30s.
The suspect was arrested overnight in a hotel and is not currently enrolled as a student at Brown University, a law enforcement source told the BBC’s US partner CBS News.
On Saturday police released CCTV footage of a male suspect, walking away from the scene of the shooting wearing all black clothing.
There is no weapon visible in the video, and his face is covered. Officials also say a firearm was not found in a sweep of the building on Saturday.
Some witnesses reportedly told officers he may have been wearing a camouflage grey mask.
One person was arrested before police determined they were not involved in the shooting and released them.
What is the latest?
In a statement released by the university on Sunday, Ms Paxson said some areas of campus were still restricted as police continued their investigations.
She said around 2,000 students were relocated to safe locations overnight, adding that she was “deeply moved” by students and locals who opened up their homes.
Brown University said all remaining exams, papers and projects would not take place as scheduled.
US President Donald Trump, speaking to reporters as he returned to the White House from attending the annual Army and Navy football game, described the shooting as “a terrible thing”.
“All we can do right now is pray for the victims and for those that were very badly hurt,” he said.
