The convoy of Kerry, who arrived in New Delhi to participate in the Second Indo-US Strategic and Commercial Dialogue, was heading to the hotel in Chanakyapuri in south Delhi when it was stuck in the traffic jam near Satya Marg on Monday, an official said.
Senior Delhi Police and traffic officials declined to share details of the incident claiming it was a 'security matter'.
Mediapersons, accompanying Kerry's convoy, posted on social media pictures of vehicles stuck up.
Officials sought to downplay the incident saying the convoy was not stuck but had only slowed down due to heavy traffic and rainfall.
The capital received heavy rains in on Monday evening with the Safdarjung observatory recording 15.2 mm rainfall while the reading at Palam observatory was 8 mm.
Vehicular movement was affected across the city with traffic crawling at various major intersections.
