Heavy traffic in central Delhi, including ITO, on Thursday morning made it difficult for the commuters to reach their destination on time. The traffic police said they received several calls regarding traffic congestion near ITO, Rajghat and Delhi Gate, which are in close proximity to the Hyderabad House, where Prime Minister Narendra Modi held talks with his Nepalese counterpart Pushpakamal Dahal 'Prachanda', who is on a four-day visit to Delhi.
