Hello. Today as Rwanda prepares for a presidential election,

we go in search of anyone willing to admit they won't be voting for the incumbent, not an easy task.

Familiar sites in Mexico, a Mariachi band, a shrine to the Virgin Mary, and pictures of the dead and the disappeared, lost to the country's vicious drug war.

We visit the great white wilderness of the Greenland ice sheet, only to find it looking rather grubby and full of puddles these days.

Our correspondent in Moscow has hit upon a new way of trying to decode Russian attitudes to the rest of the world.

It's almost 16 years since international forces entered Afghanistan to try and force the Taliban out of the country.

In America, discussion about how it can win its longest war has been replaced with talk about

how it can minimize losses and avoid losing altogether.

A long anticipated announcement about additional US troops has so far not materialised,

and the Trump administration is yet to reveal its strategy.

In Afghanistan, the country's security forces continue to expand and modernize with the help of their allies,

and that includes its fledgling Air Force which as

Justin Rolat found has become a particular source of pride. There is something

almost lascivious about the way Major Hamayun Zarin touches his aircraft as he goes through the

pre-flight drill. He clearly loves the plane stroking, no, caressing it as we talk.

I guess you develop quite a bond when you fly something like the A-29 into battle.

It's a fighter plane, single propeller, not jet.

Think Spitfire rather than F-16, but a vicious beast nonetheless.

There's a 12 millimeter machine gun on each wing, a 20 millimeter cannon under the fuselage, and it can fire rockets and precision-guided

bombs.
