MEXICO CITY (Reuters) - Masked demonstrators threw Molotov cocktails and shot fireworks at police near Mexico City's airport on Thursday as thousands protested President Enrique Pena Nieto's handling of the apparent massacre of 43 trainee school teachers.
Police in riot gear faced down around 300 protesters near the airport a few hours before three major marches in Mexico City set off in support of the students, apparently murdered after their abduction by corrupt police on Sept. 26.
No one was injured in Thursday's clashes, police said.
Mexico has been convulsed by protests since the 43 students were taken from the southwestern city of Iguala by police working with a local drug gang and then very likely incinerated, according to the government, which is still investigating the incident.
The three marches took place on the 114th anniversary of the day the Mexican Revolution to overthrow dictator Porfirio Diaz began in 1910. The protesters included relatives of the students. Many carried banners with slogans attacking the government such as "the state did it."
"I'm here because I don't want anything like that to happen to my daughter," said domestic worker Alma Hernandez, 30, who was accompanied by her six-year-old daughter. "By coming with me, she knows that not everything in the world is rose-tinted, and that not everything the government tells you is true."
The government has been plunged into crisis by the violence in Iguala, where six people, including three other trainee teachers also died on the night in question.
Exacerbating public discontent has been a scandal over a lucrative rail contract that has embarrassed the president.
Earlier this month, the government abruptly cancelled a $3.75 billion (2.38 billion pounds) high-speed rail contract awarded to a consortium led by China Railway Construction Corp Ltd, partnered with a group of Mexican firms including one known as Grupo Higa.
It then emerged that a subsidiary of Grupo Higa owned a luxury house that Pena Nieto's wife, Angelica Rivera, was in the process of acquiring, raising questions about the tender and prompting her to announce on Tuesday that she would give up the house.
Neither she nor her husband have explained why a member of the winning bidders from the rail consortium was also the owner of the family's house.
