The battle for the last stronghold of the Islamic State of Iraq and the Levant (ISIL, also known as ISIS) group in Raqqa, Syria, has entered its fourth day.

 

Fighters from the Syrian Democratic Forces (SDF) are moving slowly into the city.

 

An estimated 150,000 civilians are trapped there. Aid agencies face a major challenge to care for them.
