In pictures: Earth Hour around the world
- Published
Landmarks and city skylines around the world have been plunged into darkness for an hour to mark Earth Hour, the annual switch-off to raise awareness about climate change. Here before and after pictures show the National Library of Belarus.
In Beijing, an LED sky screen was demonstrated before the switch-off, which took place at 20:30 local time in each place.
The event, now in its seventh year, produces unusual views of iconic landmarks like the Welcome monument in Jakarta.
In many places, people lit candles as the lights went off.
Organisers say the event has played a part in drawing people's attention to energy use.
In Singapore, dancers produced kinetic energy to power an outdoor film show.
Moscow's Kremlin took part in the event for the first time, as did Tunisia, Surinam, Rwanda and the Palestinian territories.
In Sofia, Bulgaria, Earth Hour saw a performance by fire acrobats.
Environmental group WWF says Earth Hour has become the world's largest demonstration of support for action on carbon emissions.
