Syrian activists say 25 killed in government airstrike
Opposition activists in Syria have said that 25 people have been killed in a government airstrike in the north of the country.
They said two children were among those who died in al-Bab - a town just to the north-east of Aleppo.
Activists posted footage online purporting to show the aftermath of the strike, but it has not been independently verified.
