Overnight missile and drone attacks by Houthi forces on Yemen's Marib city and the coastal town of al-Makha (Mocha) killed several people, according to local media.
A strike on Sunday targeted the outskirts of al-Makha, a port town on Yemen's Red Sea coast, while another hit a main road in the town.
Four people were killed and eight wounded in the overnight attacks, according to state media and the director of al-Makha airport.
The government media office in Marib said six ballistic missiles and four drones targeted residential areas in the city on Saturday evening, wounding four people and damaging homes and civilian infrastructure.
Port operations at al-Makha have been suspended due to days of airstrikes, said Abdulmalik al-Sharabi, general director of the government-run facility, on Saturday.
Meanwhile, Yemen's military said it conducted 181 operations against Houthi positions in several provinces over Saturday and Sunday, killing and wounding dozens of group members.
The Houthis confirmed four members were killed but provided no further details on the circumstances of their deaths.
Yemen had seen a relative lull in fighting since April 2022 in a nearly 12-year conflict between government forces and the Houthis, who have controlled the capital Sanaa and many other cities and provinces since September 2014.
Earlier this month, the Houthis carried out attacks on military camps in Marib and Hadramout, killing at least 30 government soldiers, in the bloodiest incident in the conflict in years. Fighting has since resumed in several provinces, including al-Jawf, al-Dhalea, and Taiz.
