CLEVELAND (Ohio) • At least eight people were injured yesterday following an apparent shooting at Ohio State University, media reported, with the Columbus campus on lockdown.

One person was in critical condition, CNN reported, citing the Columbus Fire Department. NBC earlier reported that two were in stable condition and the conditions of the others were unknown.

Live television reports from the campus showed a massive police presence, including armed police, ambulances and fire engines.

Students at the university were told to "Run, Hide, Fight", as an "active shooter" alert was issued by the university's emergency management on Twitter.

The alert was issued for Watts Hall at 19th and College Street, reportedly a classroom building at the huge campus, which has some 66,000 students, in the Ohio state capital of Columbus.

At press time, the BBC reported that the alleged shooter had been killed.

Elsewhere, hours earlier, one man was killed and nine others were shot in Bourbon Street, New Orleans, a tourist destination that was more crowded than usual after the conclusion of a major college football game, The New York Times reported.

The victims ranged in age from 20 to 37. Eight of the 10 victims were men and two were women, the Times reported.

In a news conference on Sunday, the city's police superintendent said the shooting had taken place in the early hours that day, New Orleans time, in the French Quarter.

He did not say whether they had identified a suspect in the shooting.
