Seven people, including four children, were killed when mortar shells hit civilian homes in the Somali capital, Mogadishu, witnesses have said.
Abdinur Hashi, a resident in the Hodan district of Mogadishu, said a father, mother and their two children died in one home, and a mother and her eight-year-old child died in a nearby house. A third child also died after suffering serious injuries caused by shrapnel.
The bodies were wrapped in white shrouds at daylight.
Mr Hashi called the violence a "catastrophe".
Security in Mogadishu has improved markedly over the past year, after African Union and Somali troops pushed al-Shabab insurgents out. But indiscriminate mortar and bomb attacks still take place.
