The third anniversary of the Army Public School carnage that claimed lives of 147 persons, mostly schoolchildren, is being observed today. People are tweeting in solidarity with the APS martyrs and their families and are paying tribute to children who went to school but never came back. Here are some of the most heart-wrenching tweets below: How can we ever forget? This is a tragic reminder to all of us to stop feeding the monsters who don’t think before killing children! May the world never ever have to see a day like this again. Ameen. #APSPeshawar pic.twitter.com/cZOVxJBu9g — Mahira Khan (@TheMahiraKhan) December 16, 2017 Today I pray no child and no parent, from any nationality or any religion, would have to go through this ever again. #16December2014 #APSPeshawar pic.twitter.com/KujYtrQByP — Sana Mir (@mir_sana05) December 16, 2017 A wife who looses her husband is called a widow, a husband who looses his wife is called a widower, a child who looses its parents is called an orphan BUT there is no word for a parent who looses their child, THATS HOW AWFUL THE LOSS IS !!! #APSPeshawar — HAPPY LATE BDAY SAMMOOWAHHH❤️❤️❤️❤️ (@itsmeee145) December 15, 2017 https://twitter.com/Patronus_Doe/status/941746357492224001 We hold the children of the Army Public School in Peshawar close to our heart.
