ANKARA, Turkey -- A prominent lawyer and human-rights defender, who faced a criminal charge of supporting Kurdish rebels, was killed Saturday in an attack in southeast Turkey in which a police officer also died, officials said.
Tahir Elci was shot while he and other lawyers were making a statement. Two policemen and a journalist also were injured.
It wasn't immediately clear who was behind the attack, and there were conflicting reports about what led to it.
Interior Minister Efkan Ala and other officials said the assault was against police officers and that Elci died in an ensuing clash. However, the Diyarbakir Bar Association said the lawyer, who was Kurdish, was the target of the attack.
Elci, 49, was the head of the bar association in the mainly Kurdish city and was a human-rights activist.
He was briefly detained and questioned last month for saying during a news program that the Kurdistan Workers' Party is not a terrorist organization. Soon after, he was charged with making terrorist propaganda and was facing more than seven years in prison.
Turkey and its allies consider the Kurdistan Workers' Party to be a terrorist organization, and the government has stepped up attacks against it in recent months. The organization has been fighting for autonomy in southeastern Turkey since 1984.
Ala said the attack began with two people firing at police from about 109 yards away from where Elci was speaking. A policeman died in that attack. Ala said Elci died soon after in a clash between the police and the assailants.
Prime Minister Ahmet Davutoglu spoke of two possible scenarios.
"One possibility is that after this terror attack, the assailants assassinated Mr. Elci," Davutoglu said. "A second possibility is that ... Elci got caught in the crossfire."
Davutoglu vowed to find the culprits through a "transparent" investigation and promised no cover-up.
A government official said four inspectors have been assigned to investigate the case, adding that the government was "determined to shed light" on the attack.
He said authorities believe that Elci was caught in the crossfire but were not ruling out "the possibility that a third party directly targeted him." The official could not be named because he was not authorized to speak publicly on the matter.
Elci had said through his Twitter account that he had received death threats because of his televised comments in which he defended the rebels.
Authorities declared a curfew in the Sur neighborhood where the attack occurred -- a scene of frequent clashes between security forces and Kurdish youths.
Protests later broke out in Diyarbakir and elsewhere denouncing the killing.
In Diyarbakir, police used pressurized water against protesters who hurled rocks and firecrackers. Police also dispersed hundreds of people who had gathered in central Istanbul chanting: "We are all Tahir, we are all Elci."
At the time of the attack, Elci and other lawyers were speaking about the destruction caused to a historic mosque by the clashes in Sur. Elci had strongly advocated an end to the renewed violence between the Kurdistan Workers' Party and security forces.
The U.S. Embassy expressed shock over Elci's death, calling him a "courageous defender of human rights."
"Our condolences go to his family, that of the policeman killed and to all of Turkey. A terrible loss," the embassy said on Twitter.
Elci was the lawyer for Mohammed Rasool, a journalist who has worked for The Associated Press and other media organizations. Rasool was arrested in August in Diyarbakir while reporting for Vice News and is still being held.
