Obama, who is in town for international talks to curb climate change, was joined at the site by French President Francois Hollande not long after Air Force One touched down around midnight local time.

After solemnly placing the rose among the flowers and  candles at the makeshift memorial, Obama stood silently in tribute, his head bowed and his hands clasped in front of him.

Afterwards he walked away with his arms around Hollande and Paris Mayor Anne Hidalgo, who was also present.

He did not make remarks. Obama has made a concerted effort to show U.S. solidarity with France after the Nov. 13 attacks, which killed 130 people.

By visiting the memorial so soon after his arrival in Paris, Obama signaled the importance he placed on continuing to show support to the people of France.
