Angelina Jolie is giving fans insight into a recent trip to Pakistan, where she was able to witness the "devastation caused by severe flooding."
Jolie, 47, shared several photos and infographics on social media Thursday, detailing the recent flooding that Pakistan Prime Minister Shehbaz Sharif has called "the worst in the country's history," per CNN.
The floods have left 1,100 people dead since mid-June, according to the country's National Disaster Management Authority, and over a third of the country is now underwater following torrential monsoon rainfall, which is reportedly 10 times heavier than usual.
"Last week I was in Pakistan with @rescueorg and local organizations, to witness the devastation caused by severe flooding which submerged 1/3 of the country's land," Jolie wrote, tagging the International Rescue Committee.
Jolie — who has been United Nations Special Envoy for Refugees since 2011 — referenced the 33 million Pakistani people impacted by the flooding, as well as the 6 million in need of emergency assistance.
In images within her post, the Oscar-winner can be seen looking out from an aircraft and speaking with residents — including young children. According to CNN, around 400 of those to have died in the flooding are children.
"Pakistan also still hosts over a million Afghan refugees who are unable to return safely due to the current situation," Jolie shared with her followers. "Those I was able to reach were still in shock from having fled the Taliban, and now knowing the country they have fled to is in an emergency."

Jolie called the level of trauma of those she met "severe," and encouraged her fans to educate themselves on climate issues.
"Please learn and follow what is happening. Be aware of the climate catastrophe that we are seeing more regularly," Jolie wrote. "Push governments to understand that lack of fair trade, rising emissions and failure to address conflicts are causing more death and suffering to millions of families around the world."
