Kathmandu: As clashes between Hindu and Muslim communities in the Kaptanganj area of Sunsari district threatened to spread to other parts of southern Madhesh province, the District Administration Office (DAO) of Siraha on Thursday imposed an indefinite curfew in parts of the district. Siraha Chief District Officer Surendra Paudel issued the curfew order effective from 2 pm local time on Thursday until further notice. Although police believe the security situation has improved, they have not ruled out the possibility of renewed clashes without heightened security. The curfew in Sunsari covers the entire areas of Inaruwa Municipality, Duhabi Municipality, Bhokraha Narsingh Rural Municipality, Koshi Rural Municipality, Gadhi Rural Municipality, Dewanganj Rural Municipality, Harinagar Rural Municipality and Barju Rural Municipality. In Ramdhuni Municipality, the curfew covers Wards 1 and 5 within the same 200-metre corridor along the highway.
