Kuwait has released two members of the Al-Sabah ruling family after holding them for two days allegedly over tweets deemed critical of the government, Aljazeera reported.
Sheikh Abdullah Salem Al-Sabah was released late on Friday, while Sheikh Nawaf Malek Al-Sabah was freed on Saturday afternoon.
"I asked them (police) to refer me to the public prosecution to defend myself from the horrifying accusations, but they insisted that I sign a pledge and they released me," Sheikh Abdullah said on Twitter.
Sheikh Nawaf's lawyer Khaled al-Suwaifan said on Saturday that his client was released but provided no details.
Sheikh Abdullah said he was questioned by the secret service police on accusations of insulting Emir Sheikh Sabah al-Ahmad Al-Sabah and instigating against the regime.
He is the grandson of the emir's half-brother, the late Sheikh Abdullah al-Ahmad Al-Sabah.
The two young royals have written tweets sympathetic to the Kuwaiti opposition, which has been organising protests against an amendment to the electoral law seen as a ploy to produce a pro-government parliament in a snap December 1 general election.
Young royal Sheikh Meshaal al-Malek Al-Sabah was detained for a few days in July for expressing political views deemed offensive.
