NEW DELHI: An unidentified man fired at a protest against India’s new citizenship law near a university in Delhi on Thursday, wounding a student, witnesses said, the first such incident in the capital during more than a month of demonstrations.

Witnesses said the man holding a gun shouted slogans against the protesters near Jamia Millia Islamia University, before firing at them.

“The police stood nearby,” Ahmed Zahir, said a witness.

A photograph showed the man, dressed in a black jacket and brandishing a single-barrel weapon, standing meters away from dozens of policemen outside the university, where more than 1,000 protesters had gathered for a march.

Police later said they had detained the suspected gunman but gave no details.
