Fighters battle Houthis in Yemen
Sources said Saudi-led forces also made four air strikes on a military base near the airport.
ADEN - Heavy fighting erupted in southern Yemen near Aden airport on Friday when a Sunni Muslim militia attacked Shi'ite Houthi rebels in a push to drive Houthis from the district, residents and fighters said.
Saudi-led forces also made four air strikes on a military base near the airport, a source in the southern militia told Reuters.
A Saudi-led coalition began air strikes in Yemen on 26 March in a campaign to restore Yemeni President Abd-Rabbu Mansour Hadi to power. He fled in March, after Iranian-backed Houthi rebels seized the capital Sanaa in September and then thrust into central and south Yemen.
Aden is Yemen's commercial hub. Its airport has been closed since fighting began but its port provides sporadic access for desperately needed humanitarian aid to enter the country.
Houthis and forces loyal to former president Ali Abdullah Saleh are concentrated around Aden's districts of Khor Maksar, Crater and Moalla.
The fighting in Khor Maksar has killed four southern militia fighters and 15 Houthis so far, the militia source said.
Intense air raids by the Arab alliance were also reported overnight by residents of Saada province, which borders Saudi Arabia in northwestern Yemen. Raids also targeted a weapons storage site in Sanaa, said residents.
On Monday, Houthi fighters suffered their first significant setback in the south in two months of civil war when local Sunni militia ejected them from much of the southern city of Dalea, about 170 km north of Aden.
The Sunni militias, who call themselves the Southern Resistance, are a loosely allied group of fighters who took up arms against the Houthis.
UN-sponsored peace talks set to be held in Geneva this week have been postponed because of the heavy fighting.
