Rockets hit a market in Sudan’s capital, Khartoum, killing 18 people and leaving more than 100 wounded.
The fighting between rival military forces comes as truce talks mediated by the US and Saudi Arabia collapsed.
Wednesday’s violence around a market in Mayo in the south of Khartoum included artillery fire and aerial bombardment.
It caused the most civilian casualties in a single incident in the capital since the war began in April.
This brings the civilian death toll over seven weeks to at least 883, according to official counts – though the real number is likely to be far higher.
