A combination of photos taken at the National Mall shows the crowds attending the inauguration ceremonies to swear in U.S. President Donald Trump at 12:01pm (left) on January 20, 2017, and President Barack Obama sometime between 12:07pm and 12:26pm on January 20, 2009, in Washington, D.C. One of the first controversies of the Trump presidency involved White House Press Secretary Sean Spicer's claim that this was the "largest audience to ever witness an inauguration, period," and that "all of this space was full" from the platform to the Washington Monument. This assertion was demonstrably false, as shown by numerous photographs taken at the time. #

Teenage girls of the Long Horn Miao ethnic minority group wear headdresses as they gather for "Tiaohua" or Flower Festival as part of the lunar new year on February 6, 2017, in Longga village, Guizhou province, southern China. The Long Horn Miao are recognized for their declining practice of wrapping a blend of linen, wool, and the hair of their ancestors around animal horns or a wooden clip to make headdresses. Many young women say they now wear the headdresses only for special occasions and festivals, as the ornaments, which are attached by the horns to their real hair, have proved impractical for modern daily life. China officially recognizes 56 different ethnic minorities, and statistics show over 7 million Chinese identifying themselves as Miao. But the small Long Horn Miao community counts only around 5,000 people living in 12 villages, whose age-old traditions, language, and culture are fading. The government has invested significant amounts of money into local infrastructure and the tourism industry to try to bolster the local economy. #

A woman who told police that she and her family were from Sudan is taken into custody by a RCMP officer just over the U.S.-Canada border in Hemmingford, Quebec, on February 12, 2017. In February, Reuters photographer Christinne Muschi spent time at the end of a small country road in Hemmingford, Quebec, that dead-ends at the U.S.-Canada border, just across from another dead-end road near Champlain, New York. She was photographing refugees, who were traveling alone or in small groups and had taken taxis to the end of the road in the U.S., then walked across the border into Canada and into the custody of the RCMP. While the location is not an official border crossing, it is one of several spots that have become informal gateways to an increasing number of refugees choosing to leave the United States. Canadian advocacy groups said they were preparing for even more asylum-seekers following increased anti-Muslim rhetoric in the U.S. and public expressions of welcome made by Canadian Prime Minister Justin Trudeau. #

Displaced Iraqi women who just fled their home rest in the desert as they wait to be transported while Iraqi forces battle with Islamic State militants in western Mosul, Iraq, on February 27, 2017. Photographer Zohra Bensemra: "I took this picture in a desert on the outskirts of Western Mosul of 90-year-old Khatla Ali Abdallah after she fled the battle for Mosul. Her fearful eyes red with fatigue, Khatla was so exhausted she could not stand or even sit properly. She looked to me like she had not eaten or drank water for a long time. The moment was so emotional that I had tears in my eyes when I photographed Khatla. I felt bad because I could not do anything for her apart from taking pictures to show the world the agony and torment of people trying to flee Mosul to safety. I was sad too, imagining this woman as my own grandmother and feeling helpless to make her comfortable. When you face such a moment, you always think that it could happen to anyone of us. But despite all, Khatla looked beautiful to me, almost as if every wrinkle on her face told a story. I was fortunate to find her a few days later in a refugee camp after showing people my photograph of her. She has survived decades of turbulence in northern Iraq. She told me "the fighting there is the worst I have ever seen". She had been carried across the desert by her grandsons, under sniper and mortar fire, one of thousands who braved the difficult and dangerous journey out of Islamic State's shrinking stronghold in western Mosul. Khatla made me smile when she expressed her remorse about her 20 chickens she had to leave behind. She had looked after them even while hiding from crossfire in her house's basement. Despite all the terror she experienced under ISIS rule, it had not destroyed her humanity, she said, 'Even animals deserve life.'" #

Police officers detain a man during an unauthorized anti-corruption rally in central Moscow on March 26, 2017. Thousands of Russians demonstrated across the country on March 26 to protest corruption, defying bans on rallies which were called by prominent Kremlin critic Alexei Navalny—who was arrested along with scores of others. Navalny called for the protests after publishing a detailed report this month accusing Prime Minister Dmitry Medvedev of controlling a property empire through a shadowy network of non-profit organizations. #

Five rhinos—one male and four female—will be released into a national park in Nepal's far west in the hope of establishing a new breeding group. #

Demonstrators scuffle with security forces during an opposition rally in Caracas, Venezuela, on April 4, 2017. Venezuelan security forces quelled masked protesters with tear gas, water cannons, and pepper spray in Caracas after blocking an opposition rally against socialist President Nicolas Maduro. The clashes began after authorities closed subway stations, set up checkpoints, and cordoned off a square where opponents had planned their latest protest against both the government and the crippling economic crisis. Photographer Carlos Garcia Rawlins: "For me that was the day that made a difference, never before had I seen the protesters and police clashing men-to-men and struggling back and forward. From then, the strategy of the police changed and they never faced the protesters so close again." #
