Chhath Puja, which is mainly observed in the eastern and northern parts of India and Nepal, is dedicated to the Sun God and the ancient Vedic Goddess Usha.
Delhi Chief Minister Arvind Kejriwal and Delhi BJP president Manoj Tiwari were among the political figures who attended the Chhath Puja.
With months to go for the next Assembly elections, the AAP and the BJP have been having a go at each other on myriad issues.
On the fourth and final day of the Chhhath Puja, devotees in different parts of India thronged river banks to offer 'Arghya' to the rising sun on Sunday.
Not just the locals, the festival was observed even by 4000 prisoners and some women belonging to the minority community.
The devotees offered sweetened rice pudding (kheer), bananas and flat round bread (roti) to the Sun god on the occasion.
According to the AAP, in Kalkaji, local BJP civic body councillor- Subhash Bhadana objected to the construction of a Chhath ghat inside an MCD park in the area.
Prison officials said arrangements have been made to facilitate the Puja in all jails, specially four central jails at Muzaffarpur, Patna, Bhagalpur and Buxar.
Delhi BJP president Manoj Tiwari said AAP workers were trying to “vitiate the atmosphere” before Chhath Puja.
Plying of boats in the Ganga has also been banned from October 30 to November 3 for the safety of devotees.
The matter came to light when images of the pro forma, many of these purportedly filled up and signed by junior rank police officials, went viral on the social media.
