People around the world celebrate International Women's Day, staging protests against women's rights abuses.
The UN writes that the day, celebrated on March 8, is an occasion to commemorate achievements in women's rights and to call for further change.
The celebration dates back to the beginning of the 20th Century and has been observed by the United Nations since 1975.
Former Desperate Housewives' actress Eva Longoria has spoken about her wishes for women on International Women's Day and "every day of their lives".
John Lennon's widow and peace activist Yoko Ono has tweeted:
A global day to call for the education of all girls and women is to be held in honour of Malala Yousafzai, the Pakistani schoolgirl shot by the Taliban, it has been announced.
Her father Ziauddin and former prime minister Gordon Brown outlined plans for Malala Day as they appeared at the Women of the World Festival at London's Southbank Centre on International Women's Day.
Mr Brown said the issue of universal education for girls was in desperate need of a "liberation movement and a freedom fight for change".
Malala Day will be held on the girl's 16th birthday, July 12, and will be celebrated with a youth assembly at the United Nations in New York.It is hoped that young people from around the world will mark the day, aimed at providing education for the 32 million girls who do not currently have access.
Singers and musicians from around the world have come together for "One Woman", a song launched today to mark International Women's Day.
The song written for UN Women is a call for listeners to join the drive for women's rights and gender equality.
An Indian student who was gang-raped and murdered has been awarded the US State Department's International Women of Courage Award, a government statement said.
The case of the 23-year-old woman, dubbed "Nirbhaya" (Fearless) by the media, who was beaten, raped and tortured by six men on a bus in New Delhi in December, sparked a public outcry. She died of her injuries after being thrown out of the bus.
The award will be presented by Secretary of State John Kerry and First Lady Michelle Obama. The US State Department said:
"Known to India and the world as 'Nirbhaya', the courageous 23-year-old physiotherapy intern whose brutal gang rape on a moving bus in Delhi in December inspired widespread protests, has become the foundation of a popular movement to end violence against women in India."
International Women's Day will be celebrated in different ways across some parts of the world today.
The day is an official holiday in dozens of countries, including Afghanistan, China, Vietnam and Zambia.
