Amid the raging debate on nationalism and complaints about insult to the national anthem and flag, the Centre has asked the states to ensure "strict compliance" of the laws over respecting them.
In a communication to all states and union territories, the Home Ministry has said it has received complaints from various quarters about disrespect being shown to the national anthem and flag and asked them to ensure their honour is protected.
The central government's missive came amid the contentious debate on nationalism which was triggered by an event at the Jawaharlal Nehru University to commemorate the hanging of Parliament attack case convict Afzal Guru.
The government also frowned upon the use of plastic flags over environmental concerns.
Ensuring appropriate disposal of national flags made of plastic with the dignity it deserves is also a problem, it said.
