Clashes have killed a total of 19 people, including three children, in two Yemeni provinces, military and medical officials said Tuesday, signaling no respite to the violence in the poor Arab nation shaken by months of unrest. Even after the departure of its embattled leader of nearly 33 years, the officials said dozens of suspected Muslim militants attacked an army position in the southern Abyan province late Monday night. The ensuing gunfight left nine soldiers and six of the attackers dead. The post in the province's Doves area remains in the hands of the army. Abyan is known to be home to some al-Qaida militants, but the military officials could not say whether the attackers belonged to the terror network.
