LAGOS, Jan 16 (Reuters) - A foreign oil worker and a Nigerian serviceman were killed on Tuesday when armed men attacked a small ferry near the Bonny Island oil and gas export complex, industry sources said. Amid conflicting preliminary reports of the attack on the vessel operated by South Korean conglomerate Hyundai, one industry source said a total of four people, including one foreign oil worker and a naval serviceman, were killed. Another source said those two were killed and four more were injured.
