Two of FIFA's Twitter accounts have been hacked in the latest wave of cyberattacks claimed by Syrian government sympathizers.

A series of corruption allegations were made on the accounts of FIFA President Sepp Blatter and the World Cup.

With soccer's governing body unable to regain control of either account, the media department confirmed by email that they had been hacked, saying: "We are looking at this issue at the moment."

The Syrian Electronic Army — hackers sympathetic to Syrian President Bashar Assad — wrote messages saying it had posted the tweets.

The group also recently claimed to have hacked the Twitter accounts of the BBC Arabic service and broadcaster Al-Jazeera.
