Mourners in South Africa have held separate services for two South African civilians who were killed in conflicts in Yemen and Afghanistan.

A memorial ceremony was held Friday for Pierre Korkie, a teacher who was killed in Yemen on Dec. 6 during a U.S. raid on al-Qaida militants who were holding Korkie and American hostage Luke Somers. American officials say militants killed both men.

Separately, a church service was held for Werner Groenewald and his children, Jean-Pierre and Rode. They were killed Nov. 29 in Afghanistan when Taliban militants stormed the office of a foreign aid group, where the family also lived. Groenewald's wife, Hannelie, who was not at the office when the attack occurred, has returned to South Africa.
