At least 15 civilians, including one child, have been killed as the Saudi-led coalition resumed its airstrikes on the outskirts of Yemen’s port city of Hudaydah despite widespread international criticism over the war's impact on civilians.

According to reports by Yemen’s Arabic-language al-Masirah television, about 20 civilians were also injured during Wednesday's bombings that were launched after a brief truce since July.

The Saudi-backed forces also captured a number of towns as well as two main supply routes linking Hudaydah to the capital Sana’a and Ta'izz province, the report added.

The bombings resumed after UN-brokered peace efforts failed in Geneva last week. The talks were aborted after the UN failed to meet conditions set by Yemen’s Ansarullah movement, including transfer of wounded people to hospital for proper treatment and guarantees on the safety of the Yemeni delegation. Ansarullah also accused Saudi Arabia of planning to strand the delegation in Djibouti, where their plane was to make a stop en route to Geneva.

Delegates from Yemen’s former government and representatives of the Houthi movement held their last UN-sponsored negotiations in Kuwait in 2016 in a bid to hammer out a “power-sharing” deal, but they fell apart after the Saudi-backed side left the venue.

Saudi Arabia and a number of its regional allies launched a devastating military campaign against Yemen in March 2015, with the aim of bringing the government of former president, Abd Rabbuh Mansur Hadi, back to power and crushing Ansarullah.

Some 15,000 Yemenis have been killed and thousands more injured since the onset of the Saudi-led aggression.

More than 2,200 others have died of cholera, and the crisis has triggered what the United Nations has described as the world's worst humanitarian disaster.
