Obama Visits Myanmar

-->

US President Barack Obama headed to Myanmar on Monday for a historic visit aimed at encouraging a string of dramatic political reforms in the former pariah state.

Obama will be the first serving US president to set foot in the country also known as Burma, in the starkest illustration yet of its emergence from a long period of isolation and repression.

He is expected to praise President Thein Sein for ending a dark era of junta rule and for welcoming opposition leader Aung San Suu Kyi into mainstream politics, but also to prod the former general to go much further towards genuine democracy. 

Obama will use a major speech at Yangon University to hail "the flickers of progress" in Myanmar, the White House said.

"Today, I have come to keep my promise, and extend the hand of friendship," Obama will say, according to excerpts of his address. "But this remarkable journey has just begun, and has much further to go."

Most-liked Facebook photo of all time

It was a moving photo like countless others on Facebook, but the caption "four more years" said it all -- US President Barack Obama had won re-election, and was about to make social media history. 

After a months-long, gruelling presidential campaign fought both off- and online, Obama sealed his tech-savvy reputation late Tuesday by announcing his victory over Republican foe Mitt Romney on Twitter and Facebook with the photo.

By early Wednesday, the shot of a smiling Obama holding his wife Michelle in a loving embrace had already broken records on both social networks -- bringing to a climax a hard-fought online campaign for supporters and votes. 

"This Barack Obama photo is the most-liked Facebook photo of all time," the social network announced Wednesday, as it clocked up more than 3.5 million "likes".
