Atleast 20 civilians perished and 42 wounded due to rebel fire from Houthi Shias in a residential district of Aden, a Yemeni city which has been at the forefront of the battle plaguing the country, medical sources said.
The Houthi Shia rebels and their allies pounded the city's loyalist-held Al-Mansura district with 15 Katyusha rockets from their positions in the Dar Saad neighbourhood, loyalist forces' spokesperson Ali al-Ahmadi told AFP.
The rocket fire began before dawn when the streets were busy ahead of the daytime fast observed by Muslims during the holy month of Ramadan, Ahmadi said.
A fresh salvo of rockets later in the morning hit mourners burying some of the dead from the earlier fire, the spokesperson and witnesses said.
"Many of the wounded are in serious condition," a medical source told AFP.
Aden was the last refuge of President Abedrabbo Mansour Hadi before he fled into exile in the neighbouring Saudi Arabia in March and his loyalists have been battling to defend it against the rebels with the support of Saudi-led air strikes.
