Al-Qaeda's leader Ayman al-Zawahri has called for young Muslim men to carry out so-called 'lone wolf' attacks in the US and in other Western countries.

In an online audio message al-Zawahri said: "I call on all Muslims who can harm the countries of the crusader coalition not to hesitate."

Al-Zawahri uses the term "crusader" countries to refer to Western powers.

"We must now focus on moving the war to the heart of the homes and cities of the crusader West and specifically America," he said.
