Prime Minister Narendra Modi had appealed to observe silence after the dastardly terror attack on the Army Public School in Peshawar. Special prayers were also held in some schools with children sporting black bands, many of them carrying placards in memory of the children who lost their lives. Candles were also lit as children reflected on the tragedy in silence. "Save the Globe from cruelty, the world is one," read one placard carried by students of a school in Kanpur.
