The two who were killed were taking part in a separatist protest in the southern port city of Aden. The south of Yemen was a separate country until 1990 and Aden has long been a center of separatist activists.
An activist from the Southern Movement separatist group said:"Security forces fired live rounds on protesters, killing two and wounding five," An official at an Aden hospital confirmed the toll.
Protesters were demanding that a week long crackdown by security forces on a protest camp be ended. Nine people had already been killed during that operation according to an activist.
The government reported that seven security personnel have been injured in clashes with protesters. For more see this article.
