The topic is terrorism.

A group called HAYI said it was behind an arson attack on ambulances in London in March.

To sum it up:

Experts think a new terror network that has taken credit for many attacks should be taken seriously by foreign governments.

HAYI first appeared online in March and targets Jewish people and symbols.

What happens next?

US authorities have arrested a man who they say planned and took credit for 20 HAYI attacks.

Experts think Australia could be a target for HAYI because it has already attacked Jewish people in Europe, the UK, and Canada.

HAYI first appeared online in March and has said it was behind about 20 violent acts against Jewish people and symbols.

The US and other countries have found links between HAYI and Iran.

But HAYI works differently than Iran's main militant groups, like Hamas and Hezbollah.

HAYI is called a 'ghost proxy' for Iran because it does not have a strict hierarchy and uses local criminals for attacks.

HAYI has a more flexible structure and recruits local criminals to carry out antisemitic attacks.

The first attack HAYI claimed was an explosion outside a synagogue in Liège, Belgium, on March 9.

Police in London are investigating an antisemitic attack.

A researcher at the Institute for Strategic Dialogue says HAYI is a 'ghost proxy' directed by a 'hostile state'.

Instead of training militants, HAYI recruits petty criminals and pays them to carry out attacks.

Experts know HAYI is linked to Iran and that most attackers are motivated by money.

HAYI first used Telegram to publicize its activities, but the platform has taken down the group's channel.

A researcher thinks foreign governments should be concerned about HAYI's tactics.

While HAYI has claimed 20 attacks, some experts think it might be taking credit for crimes it did not commit.

Residents in London are watching the police operation after a double-stabbing.

A man has been arrested for alleged links to HAYI.

The US Department of Justice has arrested and charged a man for alleged links to HAYI.

The man, an Iraqi national, has alleged links to Tehran-backed paramilitary groups.

The Iranian Revolutionary Guard Corps reports directly to Iran's supreme leader and is considered a terrorist organization.

The US Attorney-General says the alleged terrorist commander is now in US custody.

The man has also been accused of plotting to bomb synagogues in the US.

The US Department of Justice alleges HAYI is a front for an Iran-backed paramilitary group.

The man is now in the custody of FBI agents.

Antisemitism has been a concern in many Western nations, including Australia.

A researcher says Australia is an obvious target for HAYI.

Iran has operated in Australia before, and HAYI is linked to Iran.

The group's attacks are getting attention, and people are puzzled.

The Jewish community is in fear, and the group's hybrid terrorism operation seems successful.

Soldiers in Belgium were deployed to guard Jewish institutions after HAYI attacks.

The Australian government has announced a royal commission into antisemitism after a mass shooting.

HAYI has claimed less deadly events, such as an arson attack on ambulances in London.

A 17-year-old boy was arrested in Paris for attempting to ignite a homemade bomb.

HAYI allegedly recruited the suspect via Snapchat and offered him money.

This is a new model of recruiting, where single-use agents are signed up online and offered money.

There is limited evidence about HAYI, but it should be taken seriously.
