input: (CNN) -- Serena Williams underlined her status as the overwhelming favorite for the women's U.S. Open title with a crushing "double bagel" win over Carla Suarez Navarro in the quarterfinals of the New York grand slam.

The defending champion, bidding for a fifth singles triumph at Flushing Meadows, beat the Spanish world No. 20 6-0 6-0 to become the first woman since Martina Navratilova in 1989 to win a women's U.S. Open quarterfinal without losing a game.

"I played well -- I played really well," world No. 1 Williams told the WTA's official website. "I was just more focused than anything.

"I like to believe there is always room for improvement though. I haven't really thought about it yet, but off the bat, I think it was very difficult to hit a big serve today because of the winds, and I didn't get my serve up as much as I wanted to. But I don't know. I do think I definitely played well tonight."

The American's latest commanding win means she has lost just 13 games at the tournament ahead of her semifinal meeting with Li Na, who is appearing in the last four of the year's final grand slam for the first time after beating Russia's Ekaterina Makarova.

"I'm still in the tournament and I'm not thinking like, 'I'm really dominant now'," added Williams. "I'm thinking I have a really tough match in the next round and want to do well."

input: Child labour refers to the employment of children in any work that deprives children of their childhood, interferes with their ability to attend regular school, and that is mentally, physically, socially or morally dangerous and harmful. This practice is considered exploitative by many international organisations. Legislation across the world prohibit child labour. These laws do not consider all work by children as child labour; exceptions include work by child artists, family duties, supervised training, certain categories of work such as those by Amish children, some forms of child work common among indigenous American children, and others.

In developing countries, with high poverty and poor schooling opportunities, child labour is still prevalent. In 2010, sub-saharan Africa had the highest incidence rates of child labour, with several African nations witnessing over 50 percent of children aged 514 working. Worldwide agriculture is the largest employer of child labour. Vast majority of child labour is found in rural settings and informal urban economy; children are predominantly employed by their parents, rather than factories.
