A son of late Libyan leader Moammar Gadhafi was briefly taken to hospital this week after his health deteriorated nearly three weeks into a hunger strike to protest his detention without trial in Beirut, a person familiar with the case said Thursday.

The health of Hannibal Gadhafi, who has been only drinking small amounts of water, deteriorated on Wednesday the person said, speaking on condition of anonymity because of the sensitivity of the case. Gadhafi, who started his hunger strike on June 3, was taken to Beirut’s Hotel-Dieu de France hospital on Wednesday after suffering a drop in blood pressure and inflammation in the spine.
