Okanga said his assailants were people he did not recognise. He did not say where the attack happened or how many people were involved. He also did not reveal what may have triggered it or whether he has reported the matter to police.
Photos accompanying the post show him with visible injuries. One image shows him bleeding. Another shows a large bandage over one side of his face, near the eye. His face appears swollen in several pictures.
Okanga said the attack would not stop him. "We shall not be intimidated, we shall not surrender," he wrote. He added that he would continue his work despite what happened.
He thanked God for surviving the ordeal. He quoted Isaiah 54:17, which says no weapon formed against him will prosper. "They may have wanted to silence me, but God is my protector," he said.
He ended his message with the political slogan "ALUTA CONTINUA! WANTAM!" and a raised-fist emoji. The slogan signals his determination to press on with his activities.
