Hundreds of thousands of people took part in rallies across the world to urge their governments to adopt major international regulations on promoting labour rights.

Each year, people take to the streets on May 1 to mark International Workers’ Day, or May Day.

Thousands attended a march in the Panamanian capital on Wednesday, attended by dozens of public and private sector unions.

“This is so important,” Angela Abrego, a union women’s group organiser from the Bocas del Toro region, told Al Jazeera.

“This way we can see that we are united.”
