A fire broke out at a factory in the Czech Republic associated with Israeli defense company Elbit Systems, according to local police. Authorities are investigating possible involvement of a terrorist group after several buildings at the site were destroyed in an early morning attack. A group has already claimed responsibility for the incident.

Al Jazeera reported that the facility, jointly operated by a Czech company and Elbit Systems, suffered extensive damage. Elbit Systems is a key supplier of weapons to the Israeli military, providing arms used in ongoing conflicts in Gaza and Iran.

A group calling itself “The Earthquake Fashion” claimed responsibility on Telegram, describing the site as a major European hub for Elbit’s operations and declaring it was now burning. The group said it acted to disrupt what it called tools of killing, asserting that it would take necessary measures against cooperating governments.
