Bana al-Abed, the seven-year-old girl who became the symbol of the tragedy unfolding in Syria with her tweets about the destruction of Aleppo, has urged Donald Trump to think of the children of Syria.

In a video posted on Wednesday, Bana asked the US president: "Have you had no food, no water for 24 hours?" before telling him "Just think of refugees and the children of Syria."

Hours earlier the seven-year-old had responded to a Tweet by Mr Trump in which he claimed his travel ban was about "keeping bad people (with bad intentions) out of country" by asking him whether she is a terrorist in his eyes.
