Two children were killed Thursday as fighting resumed between pro-government militias in Yemen's southwestern city of Taez, local officials and medical sources said.
The clashes left a number of others wounded including civilians, the sources said.
Fighting in the city has pitted militiamen from the Muslim Brotherhood-linked Al-Islah party against fighters with the Salafist movement.
Al-Islah says its military wing has launched operations to flush out Salafist fighters accused of killing some of their members.
Doctors Without Borders said Tuesday that five people have been killed and 91 others wounded in clashes between the groups since April 19.
The city of Taez is under siege by the Iran-backed Huthi rebels but controlled by pro-government forces, who are supported by a military coalition led by Saudi Arabia and the United Arab Emirates.
According to the World Health Organization, nearly 10,000 people -- most of them civilians -- have been killed and more than 60,000 wounded since the alliance intervened in Yemen in March 2015.
Rights group estimate the toll could be much higher.
