An association of journalists working in China says a number of its members have had their Gmail accounts hijacked.
The Foreign Correspondents' Club of China says writers 'in a few bureaus in Beijing' have found that their emails were being forwarded to a stranger's address. One was Associated Press; the others haven't been named.
"We remind all members that journalists in China have been particular targets of hacker attacks in the last two years," it warns in an email to its members.
"Please be very careful about what links you click on, what email attachments you open, and do run virus checks regularly."
The news comes just days after similar attacks against Google, including the infiltration of the Gmail accounts of human rights workers. The attacks prompted Google to threaten to pull out of China altogether.
