Live from London, this is Andrew Peach with NewsHour.
Good to have you with us.
Later in the programme, we're going to take you to the Russian peninsula of Kamchatka,
where a volcano has erupted for the first time in hundreds of years.
There is a lot of areas where you can't walk because it's all covered by pine trees.
And those pine trees are about waist height.
And there are a lot of bears hiding in those pines that want to steal your lunch.
Also today, the story of one man's obsession.
I kept it a huge dark secret.
I tried to push people away.
I tried to keep it to myself.
I wouldn't call it shame, but I wasn't sure if it was right or wrong.
I thought it was something I couldn't share with other people.
First, though, when a million Catholics descend on Rome for any special event,
the energy is absolutely incredible.
I was there to cover the beatification of John Paul II for the BBC in 2011.
I can still see the faces of the sharp-elbowed nuns I was thrust alongside in the huge crowd moving towards the Vatican at four o'clock in the morning.
Today, the atmosphere is even more vibrant,
with an open-air mass marking the culmination of a youth pilgrimage with people from around the world.
In his address, Pope Leo pledged his support for young people in war zones.
