KATHMANDU: Expressing his concern over the death of an Indian national in a violent protest in Birgunj of Nepal today, Indian Prime Minister Narendra Modi on Monday evening called up Prime Minister KP Sharma Oli and requested for details of the case.

India's Office of the Prime Minister tweeted that Modi also expressed his shock over and condemned the incident.

In response, Prime Minister Oli apprised Prime Minister Modi that the incident happened as Nepali security forces opened fire in self-defence, Rastriya Samachar Samiti reported, quoting Nepali Prime Minister's press advisor Pramod Dahal.

Oli further urged the Indian Prime Minister not to worry about the safety of Indian nationals in Nepal and to ensure smooth supplies of daily essentials to Nepal.

The two also exchanged views on the ongoing Tarai/Madhes agitation and the possible ways for its end, the RSS reported.

Modi, on the other hand, assured his Nepali counterpart that there is no obstacle from the Indian side for supply of essentials to Nepal.

He has "urged" Nepali leaders to "work towards ensuring an early and effective solution to the crisis," said the Office.

An Indian youth, Aashish Kumar Ram, from Raxaul of Bihar state of India, was killed when Nepali police personnel opened fire on protesters to control the situation in Birgunj of Parsa district, bordering Raxaul, this afternoon.

Violent protests broke out in Birgunj after police used force to remove the cadres and supporters of agitating Madhesi parties who were staging a stage-in protest at the no-man's land at Nepal-India order in order to let over 200 Indian cargo vehicles stranded on the Nepali side for about six weeks.

India's Ministry of External Affairs had also expressed concern over the death of Indian national, saying he was innocent, while Nepal's Ministry of Home Affairs said in a statement that the person was killed in police action as a mob threw petrol bomb and attacked a police post in Inarwa of Birgunj.

Modi had visited Bihar to address elections rallies this afternoon.

At the same time, PM urged Nepalese leaders to work towards ensuring an early & effective solution to the crisis.
