Vigils across Pakistan remember the schoolchildren killed by Taliban militants a month ago.
Gunmen broke into Peshawar's Army Public School, and shot dead more than 130 students as well as several teachers.
In capital Islamabad, politicians stood with children, chanting "terrorism is not acceptable".
(SOUNDBITE) (English) OPPOSITION PARLIAMENTARIAN SHAZIA MARRI SAYING:
"We all feel that terrorism is a menace and Pakistan needs to work towards elimination of terrorism."
The government is battling a surge of Islamist militants -- Pakistanis are used to assaults on security forces.
But the outright attack on children on December 16 has sent shockwaves across the country.
