The United States says one civilian was killed and three were injured in a US air strike in Somalia in February, the second such admission since it launched quarterly reports on civilian casualties in its Africa operations.
In a report, US Africa Command (AFRICOM) said a verification of the facts and circumstances about a February 2 air strike triggered by allegations of civilian deaths established one civilian had been killed while three were injured.
"Unfortunately, we believe our operations caused the inadvertent death of one person and injury to three others who we did not intend to target," AFRICOM's commander, General Stephen Townsend was quoted as saying.
"We work hard to prevent civilians from getting hurt or killed during these operations designed to bring increased security and stability to Somalia."
The air strike, AFRICOM said, took place in the vicinity of Jilib, an area about 380km south of Somalia's capital Mogadishu.
The US has been conducting air strikes in Somalia for years to help defeat the militant group al-Shabab.
