The police on Sunday evening shot and killed the man suspected of killing a woman and injuring 29 other people near a Berlin gay Pride celebration after he charged at officers with a weapon, the German authorities said.

The man, a 21-year-old German citizen whose family members migrated from Lebanon, had been the subject of a protracted nationwide manhunt since the Saturday evening attack. The suspect used a rented van and what appeared to be a machete in the attack, which German officials called an act of Islamist terrorism.

In a brief statement, the police said they had tracked the suspect to an area in a western corner of the city where residents maintain large garden patches. After officers shot him, emergency responders tried to revive him, but he died at the scene, the police said.

The authorities said that their investigation into the attack was continuing, even after the death of the target of their manhunt, and that they had been looking for additional suspects.

“There is one other person under consideration, though nothing has been substantiated so far — nor has that line of inquiry been closed,” Alexander Dobrint, the federal interior minister, said in a televised interview on Sunday evening with the public broadcaster ARD. “Further measures are being taken, but we do not currently believe there is any further threat.”

From the time of the attack late on Saturday night, in the city’s central Tiergarten park, the authorities had scoured Berlin, along with the nation’s rail stations, airports and border crossings. They were searching for a man the police had identified only as Abdul B., in keeping with German privacy laws.
