Pictures Of The Week: Kate Middleton, Barack Obama And A White Bengal Tiger

Former Taliban militants line up with their weapons to attend a joining ceremony with the Afghan government in Laghman province, east of Kabul, and Sculptor Roger Mackay puts the finishing touches to Madame Tussaud's first ever ice sculpture of Twilight's Bella Swan in London.

Pakistani scavenger children paint their faces with talcum powder, three polar bear cubs play on snow at the Moscow Zoo, and President Barack Obama and Prime Minister David Cameron attend the Mississippi Valley State game against Western Kentucky.

Finally, a white Bengal tiger yawns at the Dusit Zoo in Bangkok, Labour leader Ed Miliband and London Mayor candidate Ken Livingstone travel on a bus to London Bridge, and Women's Team GB hockey captain Kate Walsh watches the Duchess of Cambridge playing hockey.

It's pictures of the week.
