Fierce clashes between pro-government fighters and Houthi militants continued on Saturday in Yemen's port city of Aden a day after the popular resistance advanced on key frontlines, local sources said.
The Houthi militants stationed on the Soulaban Mountain shelled the resistance after its fighters tried to advance on the road linking the Mansoura and Khour Maksar districts, they said.
There were casualties from both sides but no statistics were given, they added, coinciding with warnings of persistent aggravation of the humanitarian situation in conflict areas including Aden.
Organizations repeated warnings the situation is still catastrophic as millions of people are in need for emergency medical help and food.
Battles between the pro-government forces and popular resistance from one side and the Houthi militants and forces loyal to the former president have been continuing for months.
They broke out after the Houthi militants with support from the former president had ousted the transition president and government.
Thousands of people including many civilians have been killed and injured and hundreds of thousands of families have been displaced due to the violence.
Moreover, the country has been facing the worst lacks of supplies especially fuels, foods and medicines. The lacks are also blamed on a blockade on all Yemeni ports which was imposed by Arab countries as part of the military operation against the Houthi militants.
The operation was launched on March 26.
