There are some 370,000 children suffering from severe malnutrition that weakens their immune system, and 1.5 million more suffer from malnutrition, according to UNICEF. The effects of war can be seen in Thawra hospital, where parents come seeking help for their starving and dying children. In April, 10-20 children a month were taken there, and figure has increased almost tenfold over the past few months. The center now sees about 120 small patients per month.

The UN delivers emergency food aid for four million people every month, O'Brien added, but they need to send even more.

The man claiming to be Bill Clinton's abandoned son says that he has promised his five children that they will meet the former President - their 'grandfather' - one day.

Danney Williams, 30, uploaded a new video to YouTube on Tuesday in which he says he regularly tells his children that Clinton is his father.

'Recently I have been telling my kids that their grandfather was the president of the United States and they're amazed by it, they're like "No. Is it for real?" I tell them yes, he is my father and I will make sure you get to meet him one day,' he says in the video.

He also says that growing up, his family would receive 'seven $100 bills' each month by mail, but it all stopped when Clinton became president.

At one point in the video Williams said he got no help from the Clintons during his upbringing, but at another he says his mother regularly got 'seven $100 bills' placed in her mailbox and he received Christmas presents from the former first family.

Williams has long claimed that his prostitute mother met Clinton when she was working on the streets of Little Rock, Arkansas. He claims she told him they had sex 13 times.

He said that it's 'unfair' that Clinton has not welcomed him into his life, but that their relationship was 'common knowledge' as he grew up in Arkansas.

'I have no doubt that I am Bill Clinton's son,' he said. 'It was common knowledge, everyone in Arkansas knew.

'Everywhere I went, they pointed out: 'It's Bill Clinton's son right there. You look like him, don't you? The ears, the mouth, the chin, the teeth, the eyes, the nose'. I see him in me.

'You can see a black Bill Clinton. When I'm brushing my hair I can see Bill Clinton with waves in his hair.

'I always feel bad about him not wanting to be in my life. Was it because I was black? Was there something wrong with me? Why do you not want to be a part of me? It made me even think of sometimes suicide.'

Williams claimed to have had several near-miss attempts to speak to the Clintons. He once went to hear a speech Bill was giving at his presidential library in Little Rock but arrived too late. Just this year during a campaign stop he said he sat front and center as Hillary spoke, but she left immediately afterwards so he didn't get a chance to speak to her.

'I put myself right in front of the podium where she spoke. She was looking right at me — eye contact. I was thinking she knew who I was.'

What made it even more galling was the fact she spoke about meeting members of the Black Lives Matter movement and how she felt for them.

'It made me wonder. She says black lives matter, so why I don't matter to her?

In a separate statement Williams denied he was coming forward now for political reasons. 'This is not about politics or money,' he said. 'For me, it is about finding the truth and understanding finally who I am and where I came from.'

Turning to the camera he pleaded with Hillary Clinton to stop ignoring him.

'Hillary, please do not deny I exist, I am your stepson. Chelsea is my sister and Bill is my father.'

He then added: 'I feel bad when Hillary called black people super-predators and that we need to be brought to heel. I'm black, I'm real and I am her stepson and I deserve the love that she has given Chelsea.

'We hear my stepmother telling the nation every day that we are stronger together. They know who I am, I know who I am, I have to meet my father, I have to know that he's willing to even accept me. I have to know.

I want to underline one observation, which I made when I was in Turkey talking with the Syrian refugees, and when we were in Greece to a certain degree, you talk with them and I haven't heard-- we haven't heard a single person saying, 'This is caused by Assad. Bashar Assad is the reason.' ... All of them unanimously say, 'This is caused by the West.' ... You go talk with these people, you will never hear one refugee, one injured person saying this is caused by Assad.
