The majority of the Ghanaian government's websites, including its main site, have been hacked and are currently offline.

A message reading "Hacked by Alsancak Tim" appeared on the sites.
On its social media accounts, Alsancak Tim describes itself as a nationalist Turkish hacker group.
The deputy communications minister said experts were working to restore the websites by the end of the day and were investigating who was behind it.
On the Facebook page of the Alsancak Tim group, which uses the tag line "injustice, oppression and war with all our might", there is a list of 11 Ghanaian websites that it says it has hacked.

The Argentine vessel had been impounded in Ghana after a financial fund said it was owed money by Argentina's government as a result of a debt default.
