Ten soldiers have been killed in a government air strike in the embattled city of Marawi in the Philippines.
The country’s defense secretary said soldiers were also wounded in the “Friendly Fire” incident on Wednesday.
Over the last week militants allied to the so-called Islamic State have engaged in street battles with the army leaving more than 100 people dead.
It was sparked by the attempted capture of a top militant leader by the army.
President Rodrigo Duterte declared martial law on southern Mindanao Island, where Marawi City is located, last week.
Most of the civilians have left Marawi, while about 2,000 remain trapped.
