[Anna Coren, Cnn:] Hello. I'm Anna Coren in Hong Kong. You are watching "News Stream." These are your world headlines. Facebook CEO Mark Zuckerberg is apologizing to users for "major breach of trust," allowing outside consultants to harvest the personal data of millions of users without their consent. He says Facebook is working to make sure user data is better protected and he even said he was willing to testify before U.S. Congress on the scandal. Russia's ambassador to Britain is holding a news conference at the embassy in London. This follows the expulsion of Russian diplomats in the wake of the nerve agent poisoning that led the former spy and his daughter in hospital. Alexander Yakovenko says Moscow has not received any information from British officials on the investigation. He also says the U.K. had stores of Novichok believed to be the nerve agent used before the attack. Police in Austin, Texas say the suspect in a series of bombings left a confession on his cellphone which he recorded before he killed himself. Federal agents say 23-year-old Anthony Conditt also had parts of bombs in his home. Investigators say so far none of the evidence points to a motive. Despite a possible trade war, Donald Trump is expected to announce new U.S. tariffs on Chinese imports. That's on top of the steel and aluminum tariffs already going into effect Friday. The European Union is hoping Mr. Trump will announce a last minute exemption for them later Thursday as E.U. leaders meet in Brussels. A group of six South Korean officials is on a visit to Pyongyang, North Korea. It comes ahead of a visit by a music group that is expected to perform there next week. Let's go straight to Alexandra Field in Seoul. Alex, what can you tell us?
[Alexandra Field, Cnn International Correspondent:] Hey, Anna. Look, this is another step forward leading to what will be a symbolic event. It may pale somewhat in comparison to the even more significant developments. We talked about the possibility of this inter-Korean summit next month and then the possibility of a sit down between the North Korean leader and the U.S. president following that. But look, this is a symbolic step forward. We literally got a team that is now on the ground in Pyongyang ready to lay the groundwork for a cultural exchange that will mean about 160 South Korean delegates traveling to North Korea. Among them, you've got a big rock band, you've got some legendary South Korean singers, even one of the country's most popular K-Pop girl band. This will be an important moment. This cultural exchanges have happened before but nothing like this has happened for more than 10 years. That was the last time that South Korea sent a group of performers to North Korea. You will remember of course that just a few weeks ago, North Korea did send its own performers to South Korea, part of the Olympic festivity, part of the falling of the tensions on the peninsula finally, and this is another step in the service of falling those tensions. This whole thing has really come together extremely rapidly following that Olympics sort of interlude that we saw there. There was the trip of South Korean envoys to Pyongyang. That was the time when they met directly with Kim Jong-un. And that's when they hatched these pretty grand plans. One for cultural exchange but also that's when they laid the plans for this inter-Korean summit that will take place next month and it was shortly after that trip that we heard from South Korean official who traveled to Washington, D.C. that the groundwork had been laid for this historic potentially summit between President Donald Trump and the North Korean leader. So, the cultural exchange is really just the first step forward in a series of steps as we watch the relationships here potentially change. But it's something that is promising certainly and it's something that people will be watching closely. It happens just next week and we will certainly be bringing it to you.
[Coren:] We can only hope that those relations can keep improving. Alexandra Field, joining us from Seoul, good to see you. Many thanks for that. This week, our special coverage takes us to India, exploring its diverse cultures and traditions. In this edition of "Destination India," we travel to Chandigarh, the capital city shared by two states, Punjab and Haryana. We gained exclusive access to the Capitol Complex which in 2016 was awarded World Heritage status by UNESCO.
[Sumit Kaur, Former Chief Architect, Chandigarh Administration:] Chandigarh
[Coren:] Still ahead on "News Stream," we will meet a young man who is trying to change the world by turning organic waste into renewable clean fuel. Tomorrow's hero is next.
