Haiti still reeling on anniversary of 2010 earthquake
Haitians call for more international aid on anniversary of disaster in 2010
Haiti marked four years since a violent earthquake shattered the impoverished nation, which is still struggling to recover from the widespread devastation that killed 250,000 people.
Haitians, many dressed in white, flocked to church services for sombre remembrances for those who perished in the tragedy on January 12, 2010, which left about a million people homeless.
But four years on, nearly 200,000 people are still living in dire conditions in temporary shelters, and residents complain of getting little help since NGOs left.
President Michel Martelly, who has faced protests over the slow pace of rebuilding, declared the anniversary a "day of reflection and commemoration".
He laid flowers early on Sunday at the site of a mass grave for many of the quake's victims. And he attended a ceremony at 4.53pm, the moment the earthquake struck four years ago.
"Thirty-five seconds ... That's all the time that was needed, on January 12, 2010, to spread darkness over Haiti. We were all in tears, plunged into despair that day," Martelly said.
