A curfew was imposed in Birgunj, a southern Nepal city bordering India, after protests over mosque vandalism by Hindu extremists led to clashes with police.
Hindu extremists had attacked the mosque on Sunday, carrying out vandalism and looting, which left the local Muslim community enraged and deeply distressed.
Large numbers of Muslims took to the streets to protest against the desecration in Dhanusha's Kamala Municipality, prompting police to use tear gas to disperse demonstrators, while several protesters were taken into custody.
Following the protests, the Parsa District Administration issued curfew orders, banning public movement on the streets across the city, as well as restricting all genres of gatherings and demonstrations, according to local media reports.
Security forces have also been authorised to open fire against those violating the curfew, officials confirmed.
Birgunj lies about 130 kilometres south of Kathmandu and is a major entry point for fuel, goods and supplies from India.
Indian authorities have also tightened security and completely sealed the Nepal border in view of the tense atmosphere in Birgunj, the reports added.
Clashes between Hindus and Muslims are uncommon in predominantly Hindu Nepal, where most Muslims live in southern border regions.
