Albania has suffered a renewed cyberattack, the country's interior ministry said on Saturday, blaming Iran which Tirana also accused of an earlier assault on its digital systems.

The national police's computer systems were hit Friday by a cyberattack which, according to initial information, was committed by the same actors who in July attacked the country's public and government service systems," the ministry said in a statement.

In order to neutralize the criminal act and secure the systems," the authorities have shut down computer control systems at seaports, airports and border posts, the statement said. 

In a tweet, Prime Minister Edi Rama denounced "another cyberattack (committed by) the same aggressors already condemned by Albania's friendly countries and allies."

Albania blamed Iran for the July attack and on Wednesday cut diplomatic ties over the affair. 

The two countries have been bitter foes for years, since the Balkan state began hosting members of the opposition People's Mujahedeen of Iran, or Mujahedeen-e-Khalq (MEK), on its soil.

Rama on Wednesday accused Iran of directing a cyberattack against Albanian institutions on July 15 in a bid to " paralyze public services and hack data and electronic communications from the government systems".

It was the first time Tirana spoke about the alleged attack.
