A German official says Chancellor Angela Merkel's website and several other German government sites have been blocked, and a pro-Russian organization has claimed responsibility.
A pro-Russian organization calling itself CyberBerkut claimed on its website Wednesday to have blocked the official sites of Merkel and the German Parliament ahead of a visit to Berlin by Ukrainian Prime Minister Arseniy Yatsenyuk. Merkel has been a leading figure in attempts to calm the Ukraine crisis.
Merkel spokesman Steffen Seibert said several government websites were unreachable Wednesday morning because of a "serious attack clearly caused by a multitude of external systems" — what is known as a distributed denial of service, or DDOS, attack.
Seibert says the attack is still being analyzed, and he did not say who was believed to be responsible.
