The Syrian Network For Human Rights reported that nearly 2,000 children were among the estimated 16,913 civilians who died in 2016 alone.
Dear Donald Trump,
My name is Bana Alabed and I am a seven years old Syrian girl from Aleppo. I lived in Syria my whole life before I left from besieged East Aleppo on December last year. I am part of the Syrian children who suffered from the Syrian war. But right now, I am having a peace in my new home of Turkey.
In Aleppo, I was in school but soon it was destroyed because of the bombing. Some of my friends died. I am very sad about them and wish they were with me because we would play together by right now.
I couldn’t play in Aleppo, it was the city of death. Right now in Turkey, I can go out and enjoy. I can go to school although I didn’t yet. That is why peace is important for everyone including you.
However, millions of Syrian children are not like me right now and suffering in different parts of Syria.
They are suffering because of adult people. I know you will be the president of America, so can you please save the children and people of Syria?
You must do something for the children of Syria because they are like your children and deserve peace like you. If you promise me you will do something for the children of Syria, I am already your new friend.
I am looking forward to what you will do for the children of Syria.
The letter, which was written by Bana and Fatemah last Thursday before the inauguration, comes on the day that Mr Trump is expected to announce a indefinite ban on Syrian refugees entering the US.
Mr Trump is expected to sign executive orders starting on Wednesday that include a temporary ban on refugees not facing religious persecution, and a suspension of visas for citizens of Syria and six other Middle Eastern and African countries.
Under the Barack Obama administration the US had pledged to let in 10,000 Syrian refugees by the end of 2016. Less than a quarter of those have so far been resettled.
“Bana and I are very upset at what (President Trump) has decided,” Mrs Abed, a 26-year-old former English teacher, told the Telegraph. “I didn’t think he would be kinder to refugees, but I was hoping he was different to (Barack) Obama and would bring a clear policy to end the war.
“Bana will Tweet the president later to convey her disappointment.”
The Abed family is currently seeking refuge in neighbouring Turkey, which supports the opposition against President Bashar al-Assad, after being evacuated by the government.
