Several pro-government fighters were killed and injured in a misdirected airstrike by the Saudi-led coalition in Yemen's province of Taiz, local sources said on Tuesday.
The raid occurred in the Sabir mountain amid raging battles between the pro-government and Houthi forces, they said.
Houthi media said at least 4 civilians were killed in airstrikes in the town of Makha.
The coalition struck Houthi forces in several parts of Taiz including Houthi reinforcements in the district of Dimnah, well-informed sources said.
In recent days, it escalated airstrikes in Taiz as the Houthi group continued to deploy reinforcements to the province.
More airstrikes were conducted in the capital Sanaa and the provinces of Sanaa, Jawf, Amran and Saada.
They coincided with battles in Jawf where locals affirmed that the government forces have retaken some positions from the Houthis.
In Sanaa, the battles in the district of Nihm continued with locals saying the government forces have retaken positions in the nearby province of Amran.
Battles erupted today in the provinces of Ibb and Dhali as the Houthis are seeking to infiltrate into southern regions.
With support from the coalition, the government forces drove the Houthis out of southern regions in mid the year.
