The Islamic State group on Wednesday claimed responsibility for an attack on a military base in Somalia's northeastern region of Puntland a day earlier, the group posted on its Telegram channel.

In its statement, Islamic State said the attack was conducted by 12 militants and two booby-trapped vehicles, adding that it killed around 22 military personnel from the Puntland forces and injured dozens of others.

Somali authorities could not immediately be reached for comment.
