only woman, was assassinated. The Jukun accused the Tiv of the murder, and further violence broke out. During this period, as many as 5,000 people may have been killed and many more forced to move. In 2001 and 2002 there were again clashes between the Jukun, Tiv, Kuteb and Fulani people of the Federation. The Aku Uka of Wukari, Dr. Shekarau Angyu Masa-Ibi Kuvyo II, was reported as saying "They (the Tiv) came here to farm; we allowed them, gave them chieftaincy titles... Now that their population has increased, they believe they are many enough to colonise us." In August 2010 there was further fighting, this time along religious rather than ethnic lines. Christians disputed the construction of a mosque at the Wukari Police divisional headquarters, and started rioting a few days before a planned visit of the Moslem Sultan of Sokoto, Muhammad Sa'ad Abubakar III. Lives were lost and property destroyed. The Aku Uka of Wukari and chairman of the Taraba State Traditional Council, Dr. Shakaru Angyu, had reportedly warned the Area Commander against the building of the mosque, which was destroyed during the disturbances. On a more positive note, Wukari traditions such as the rituals of the crocodile shrine are of interest to tourists. The annual Nwonyo Fishing Festival, which has its origins in 1826, includes boat and canoe racing, diving, swimming, and traditional dancing, and there is a prize for the person who catches the heaviest fish. The competition takes place at the Nwonyo lake, said to have been discovered in 1816 by the founder of Ibi, Buba Wurbo, and the first public festival was held during the reign of Abgumanu II (1903–1915). After a ritual to appease the gods of the river, when the fishing contest began in April 2010 the winner caught a fish weighing 318 kg.
