Berlin: German Chancellor Angela Merkel says on International Women's Day that while much has been achieved, the struggle for more equality for women in Germany and worldwide must continue.

Merkel, considered one of the world's most powerful women, said today in a video message that "many women before us have made sacrifices and fought persistently so that women would have more rights ... but there's still a lot to do."

The chancellor said that, "there are also new tasks for men", but she didn't elaborate further.

Merkel added, "Therefore today is not only a day to look back at what has been achieved, but also a day on which we say the struggle for equal rights of women continues.
