A Congolese press freedom group says a state television reporter was killed in his home by unidentified assailants.

The group Journalist in Danger said in a statement Wednesday that the reporter, Marcel Lubala, was shot three times early Tuesday morning at his home in the central town of Mbuji-Mayi. The group said his body was dragged in front of his wife, who had been tied up.

The group said Lubala appeared to be the victim of a "settling of scores." It said journalists in the region would observe a "day without the press" on Thursday.

The provincial government said several people were arrested in connection with the case but did not suggest a possible motive.

Journalist in Danger has recorded 14 journalist killings in Congo in the past decade.
