People are not happy in Sydney. They do not like a visit. A president came to the city. Some groups are not happy.
These groups want to help Palestine. They have a protest. Some people are taken by the police. Some say police are too strong.
The protest is near a big hall. Many people come to this place. They are against the visit. The leaders of the country invited the president. They want to help Jewish people. This is after a bad thing happened.
But people who protest do not agree. They feel they cannot say their mind. They see police take people. Some people are hurt. Police use spray on others. One man says police are strong.
The police boss does not agree. He says police are good. He says they stop bad things. Ten police are hurt. Police take 27 people. Some people will go to a court.
Police say 6,000 people come. Other people say 50,000 people are there. Protesters try to change police. They do not win. Now people ask about police.
