Actor Ewan McGregor confessed he doesn't understand why people have to fight each other, to resort to violence and terrorism, because while he travelled in the conflict zones, he met people who were willing to help each other.

McGregor thinks whether he was in Russia, Mongolia or Iraq, he met the same willing to help people and he felt a big contradiction in terms of the happiness about humanity.

Ewan declared he was shocked by the terrorist attacks in London, because he felt sure humanity was coming together after witnessing true acts of kindness on the road.

He explains, "We were meeting real people who lived close to roads in the middle of nowhere, who were willing to share what they had with us.

Then immediately after we got back, those children were blown up in that school in Russia. It's such a contradiction in terms of the happiness about humanity that I felt, and now what's going on in London and what went on in Iraq."

"I kinda felt that the people we met, whether they were in Mongolia or whether they were in America, weren't so very different from one another.

And it doesn't seem to reflect those people, the fact that we fight each other," McGregor added.
