MANILA, Philippines -- In Manila, they decried the president as a violator of women's rights. In Seoul, the surging #MeToo movement took to the streets. In India, where endemic violence against women has only recently become part of the public conversation, they marched toward Parliament loudly demanding their rights.

It was International Women's Day on Thursday, and as the day began in Asia tens of thousands of women ensured it could not go unnoticed.

Hundreds of activists in pink and purple shirts protested in downtown Manila against Philippine President Rodrigo Duterte, calling him among the worst violators of women's rights in Asia. Protest leaders sang and danced in a boisterous rally in Plaza Miranda, handing red and white roses to mothers, sisters and widows of drug suspects slain under Duterte's crackdown on illegal drugs.
