BANGKOK (AFP) - Thai Prime Minister Yingluck Shinawatra came under fire from her own Twitter account on Sunday when it was briefly taken over by an anonymous hacker who accused her of incompetence. Thailand's Information, Communication and Technology ministry said it was investigating the hijacking of the PouYingluck tweet feed. Yingluck, the sister of ousted former leader Thaksin Shinawatra, was lambasted on a variety of subjects in eight posts, including her response to recent serious flooding and a number of key government policies. "How can she protect the country, if she cannot protect her own Twitter account? Think about it," said the final post.
