#BBCtrending: 'We are N' - global support for Iraq's Christians
With Isis militants still in control of Mosul in Iraq, Christians there are facing repression.
The Islamic State in Iraq and the Levant (Isis) took control of the city in early June.
Militants have marked Christian houses with the letter "N" in Arabic, to single them out for harsh treatment.
On social media, thousands have taken the symbol and reversed its meaning - using it to express solidarity with Iraqi Christians.
