Mexico City, November 10 (RHC-NNN) -- Families of the 43 missing students arrived in Mexico City on Sunday after marching 195 km to demand the safe return of the students and voice their discontent over the belated investigation.

The families departed from Iguala city on November 3rd in the southern state of Guerrero, where the abduction occurred, and embarked on the march called "43x43 Movement."

Jose Alcaraz, a spokesman for the movement, said: "Today we meet our commitment of walking 195 km to demand the safe return of the 43 students." Alcaraz said the goal is also to demand that the government implement new measures to guarantee security and tackle violence in Mexico. On September 26th, the clash between students of a teacher's college and municipal police in Iguala left six people dead and led to the disappearance of 43 students.

On Friday, Mexico's Attorney General Jesus Murillo Karam said the 43 students were probably massacred and their remains burned and dumped in a local river.

The announcement sparked a new wave of protests, including demonstrations and attacks on public buildings and vehicles. Masked protesters even set fire to the ceremonial presidential palace in Mexico City's Zocalo Square on Saturday.
