Hacked: Guardian tweets spruiking the Syrian Electronic Army.
The Guardian newspaper says its Twitter accounts have been hacked, citing a claim of responsibility from the group calling itself the Syrian Electronic Army.
The British newspaper reported on its website that several of its Twitter accounts were broken into over the weekend.
It said it has since discovered the attack apparently originated from internet protocol (IP) addresses within Syria.
"We are aware that a number of Guardian Twitter accounts have been compromised and we are working actively to resolve this," said a Guardian News & Media spokesperson.
The newspaper said the Syrian Electronic Army accused The Guardian of spreading "lies and slander about Syria".
The Guardian said it first recognised it was being targeted when suspect emails were sent to staff members.
Some of The Guardian's Twitter accounts, including those focusing on books and film, have been suspended.
The Syrian Electronic Army (SEA) has claimed responsibility for attacks on other media targets, organisations and prominent figures.
Last week, it claimed responsibility for hacking into the official Twitter account of the Associated Press and sending a false tweet regarding two explosions in the White House, which briefly shook US financial markets.
