More Twitter accounts were hacked, and this time, Forbes was among the hundreds of victims.

On Wednesday afternoon, many verified Twitter accounts changed their avatars into a pin seen during the time of the Ottoman Empire, and a cover picture of the Turkish flag.

The accounts also started tweeting the same message with a YouTube video link. The text was written in Turkish, with hashtags including "Nazi Germany" and "Nazi Netherlands". The messages seemed to have promised more hacking activities next month.

"Don't test the patience of Turkish people," reads the video's description.

The affected accounts seen so far include:

- Forbes

- UNICEF USA

- Amnesty International

- Atlanta Police Department

The hack came after serious tensions erupted last week between Turkey and the Netherlands.

The dispute between the two countries sharply escalated last Saturday, as the Dutch government blocked a campaign visit by the Turkish foreign minister, prompting Turkish President Recep Tayyip Erdogan to call them "fascists."

The Netherlands withdrew landing permissions for Foreign Minister Mevlut Cavusoglu because of objections to his intention to rally in Rotterdam for a Turkish referendum on constitutional reforms to expand presidential powers, which the Dutch see as a step backward from democracy.

Turkish Prime Minister Binali Yildirim said that his Dutch counterpart, Mark Rutte, had apologized by the phone over the detention of Turkish charge d'affaires and Rotterdam consul general, the Daily Sabah reported Wednesday.
