German authorities said they arrested a young man who announced on the Internet that he intended to carry out an attack against Muslims such as the Christchurch attack in New Zealand last year, according to the Central Counter-Terrorism Office.

The office said - in a statement - that weapons had been found in the SAP house "that may have been purchased to carry out his plan to launch an attack", and that he was 21 years old, and was imprisoned last Saturday after his arrest in Hildesheim, Lower Saxony.

The young man had announced during an online communication that he was planning to launch an attack against Muslims, which was inspired by the attack in March 2019 in Christchurch, New Zealand, that killed 51 people in two mosques.

"He was intending to carry out the attack in the same manner," the office said, and police investigators also found in his electronic devices "files with extreme right-wing content."

The German authorities consider extremist right-wing terrorism the first threat to the country's security, as attacks by individuals from this trend have increased significantly in recent periods.

In June 2019, a pro-immigration deputy governor was assassinated at his home, and the suspect was close to the neo-Nazi community.

In October 2019, on Yom Kippur, a man close to the far-right attempted to enter a synagogue in Hull to carry out an attack, and when he failed to do so, he killed a woman and an employee of a restaurant before he was arrested.

Last February, in Hanau, near Frankfurt, a man killed nine people - all foreigners - in a double shooting at bars of smoking hookahs before he committed suicide.

Several other similar attacks have been thwarted in the past months.
