Tripura: The heat wave across the state of Tripura has forced the state to declare holidays from April 18 to April 23. Since heat wave across the state may cause bad impact on health of the students, this decision has been taken. All the government-run and grant-in-aid schools closed with effect from April 18 to April 23. In addition to it, the private-run schools have been requested to keep their institutions closed during that period.
