Police used pepper spray against demonstrators who sprayed paint along the route of the march to mark International Safe Abortion Day in Mexico City.
Hundreds of women marched through Mexico's capital Monday to demand nationwide legalisation of abortion, leading to clashes with police who blocked their way.
Protesters gathered near Mexico City's historic center to head to the central plaza, but were stopped by female police officers carrying shields.

Some police officers sustained minor injuries, Mexico City official Arturo Medina told local television.
The protesters want abortion to be decriminalised throughout the country of 128 million, not just in the Mexican capital and the southwestern state of Oaxaca.
Standing up for women
In addition, Mexican feminist groups have started to take a more hardline stance in the face of growing violence against women.
Ten women are murdered every day in Mexico, according to official figures, and many of the crimes go unpunished.
