The overall winning image of the competition is this emotive shot taken in 2017 by photographer KM Asad in Bangladesh.
It shows Asmat Ara, a refugee from Myanmar who looks traumatised after witnessing the violence that had taken place there.
The previous night she had entered Tenkhali Rohingya refugee camp with her family from Kumar Khali
in Rohingya state.
According to the UNHCR, more than 646,000 Rohingya refugees have fled from Myanmar since August 2017, most of them trying to cross the border to reach Bangladesh.
American photographer Mariusz Potocki captured this charming image of chinstrap penguins resting on an iceberg in the Bransfield Strait in Antarctica.
He said: 'When sailing Antarctic waters you will often see different types of icebergs. Some of these floating islands are great resting places for hunting penguins who can travel many kilometers, before jumping back into the icy water'.
