Four persons, including a child, were killed in clashes on Tuesday in south Yemen between security forces and separatists, who have called for “civil disobedience” in protest at the country’s presidential polls, officials and medics said.

A 10-year-old child was killed when militants from the separatist Southern Movement traded gunfire with police near the election commission headquarters in Aden’s Dar Saad neighbourhood, residents and medics said.

Southern Movement gunmen killed a policeman in Mansura, also in Aden, the main city in the south, a security official said, adding that two others were wounded in Dar Saad. In the southeastern city of Mukalla, separatists attacked a polling station killing a soldier, a military official said.
