The United Kingdom has closed its embassy in Tehran for now. This is because of serious problems in Iran. The ambassador and staff have left. They will work from another place. This news came on Wednesday. It shows that Iran is not safe.
The UK decided this after checking the security situation. Iran is having big protests. These are the worst since the government started. At the same time, the US President, Donald Trump, spoke to the protesters. He said help was coming.
Iran warned its neighbours. They said they would attack US bases if the US attacked them. This has made tensions in the area very high.
US officials are talking about what to do. They are thinking about attacking Iran. However, they have not decided to send many soldiers. The US might target specific places. These places are thought to be responsible for stopping the protests.
The news of a possible US attack has made markets nervous. Gold prices have gone up a lot. People are buying gold because it is safe. Oil prices are also unstable. This is because traders think there might be problems with oil supply.
A US attack could spread the problem to other countries. Britain and the US are moving some staff from their bases in the Middle East. This is a warning sign. European officials think a US attack is likely. They think it could happen soon. The next few days will be very important.
