As thousands of Muslims gathered at the iconic Jama Masjid to sip water and eat after hours of fasting, a group of non-Muslims joined them to learn about how Ramadan is observed in Old Delhi.

Their visit was organised by 'Delhi by Foot' which usually holds walks around some of the less explored and historic parts of New Delhi, often including experiences like tasting the famous street foods of the Indian capital.

At the sound of firecrackers and prayers being recited through loudspeakers, people lifted their glasses of water to quench their day-long thirst.

Families rejoiced and ate food for the Iftar, the breaking of the Ramadan fast, after having successfully fasted for more than 12 hours, from sunrise to sunset.

The Delhi by Foot group, which was set up by Ramit Mitra more than a decade ago, gathered close to share the experience.

Mitra told the Associated Press that their 'Ramadan Walk', has had a lot of takers, as many people who have lived in the populous city all their lives hadn't even seen the famous mosque.

Many were eager for a chance to better understand the significance of Ramadan and the various rituals associated with breaking the fast.

For Mitra, the walk to Jama Masjid during Ramadan allows people to have a "live" experience of something they usually only see on television.

And some of the main attractions of the walk are the sizzling kebabs and Indian sweets that are sold by food stalls outside the Jama Masjid soon after Iftar.
