Crying in pain and holding onto their parents

The procedures were carried out on boys who had not yet reached puberty at a make-shift clinic in Kabanjahe on Thursday.

In accordance with tradition, young Indonesian Muslim men must be circumcised before puberty, Xinhua reported.

The photographs show a contrast of emotions, including shots of young boys crying in pain as the act was carried out.

In one photo, a patient in a bright orange t-shirt has his mouth wide-open as he screams, as two nurses and a table stacked with medical equipment can be seen around him.

However, the next picture portrays another equally powerful emotion, as the boy's father lovingly cradles his son in his arms. 

In the photo, the young boy is no longer crying, and instead has stretched his arms out to wrap them around his father's neck.

The full range of emotion shows in the pictures is completed with another image, which features a young boy smiling from ear to ear. 

The camp is full of refugees created after recent eruptions of the Mount Sinabung, the country's most active volcano.

In 2014 it was reported tens of thousands of people had become refugees after the blasts, which blanketed dozens of towns in ash from the then-daily eruptions.

The most recent string of eruptions ended in October 2014, after spewing ash into the air and causing landslides in nearby towns and villages.
