AlHijjah 05, 1436, September 19, 2015, SPA -- U.N. Secretary-General Ban Ki-moon Friday called for a 24-hour ceasefire on September 21, the International Day of Peace. "On this day, in the lead-up to the Day of Peace, I am asking all partners to lend their voices to this call for a laying down of arms, and to work non-stop in the days to come to bring about a 24-hour ceasefire on September 21," Ban said in a statement. "Let's make this International Day of Peace a day without violence, and a day of forgiveness. If, for one day, we can live in a world without aggression and hostility, we can imagine how much more is possible," Ban said. The theme of this year's day of peace is "Partnerships for Peace – Dignity for All," which intends to highlight the importance of all segments of society to work together to strive for peace.
