The Uzbek president's daughter Gulnara Karimova has again used Twitter to launch a personal attack against her younger sister, Lola Karimova-Tillyaeva.

Karimova's latest tweets, posted over the weekend, allege that her sister is much wealthier than the Swiss business magazine "Bilan" estimated in a recent survey.

Karimova-Tillyaeva has rejected reports she and her husband are among Switzerland's richest couples.

Karimova claimed on Twitter that "Bilan" had not considered all of her sister's wealth and multimillion-dollar properties in the United States and Dubai.

Karimova previously blamed her sister for many of the internal problems that she says have beset the family.

Karimova's Twitter account has been disabled and enabled several times in recent days amid reports of close associates being arrested, her media outlets being taken off the air, and her media holding company being investigated for bribe-taking.
