Deadly flash floods in Nepal have left hundreds missing, including tourists from the United States, India, the United Kingdom, and Malaysia.
Bihar has been put on high alert after floodwaters from Nepal entered the Gandak river and reached the Gandak Barrage, prompting authorities to open all 36 gates to control the surge.
The barrage is situated at Valmikinagar in West Champaran, the northernmost district of the state that shares a border with Nepal.
