The attacks occurred early on Wednesday near a Kuda Island village, which is located in 15km from Kuda, a senior al-Shabab official Sheikh Ibrahim said. He confirmed that six people were killed and dozens of others injured in the latest airstrikes.
The official added that the US-led aerial attacks were also carried out in the south of the African country near the port city of Kismayo.
Washington has been carrying out assassination drone attacks in other countries including Afghanistan, Pakistan, and Yemen.
The United States claims the CIA-run strikes are aimed at militants. But witness reports and figures offered by local authorities indicate the attacks have led to massive civilian deaths in these countries.
The UN has condemned the US assassination drone strikes, saying they pose a challenge to international law.
