Two men accused of carrying out a killing spree that rattled Oklahoma's black community over the weekend have made their first court appearance by closed-circuit television.

Jake England, 19, and Alvin Watts, 32, were arrested early Sunday, following a spate of attacks on Friday that left three people dead and two more critically wounded.

Neither man appeared with an attorney, and a judge set a bond at $9.16m apiece. Both are being held on suspicion of three counts of first-degree murder, two counts of shooting with the intent to kill and one count of possession of a firearm in the commission of a felony. They will be formally charged at a later date.

Police identified those killed as Dannaer Fields, 49, Bobby Clark, 54, and William Allen, 31. The wounded individuals were men who have not been identified.
