Preliminary reports say at least two people are believed to be dead and as many as 20 injured after shots were reportedly fired on the campus of Brown University in Rhode Island, according to Sky's US partner NBC News.

The incident is believed to be unfolding near an engineering building on the campus, according to the school's alert system.

Providence Police and the Rhode Island State Police are responding.

It is unclear at the moment whether arrests have been made.

Brown University says no suspects are in custody and that additional shots may have been fired.

However, US President Donald Trump said in a message on Truth Social that a suspect is in custody and that he is being briefed on the situation.

He also said the FBI is on the scene.

The shooting was reported near the Barus & Holley building, a seven-storey structure that houses the School of Engineering and Physics Department, according to the school's website.

It includes 117 laboratories, 150 offices and 15 classrooms.

Officials were still gathering information from the active scene, said Kristy DosReis, chief public information officer for the city.
