The families of Islamists held by the Lebanese authorities for their alleged links with Fatah al-Islam staged another protest on Tuesday, demanding the release of the prisoners.

Around 200 women and children took part in the protest outside the U.N. headquarters in downtown Beirut.

Some held balloons that read "Free my Dad." Some other children were blindfolded and handcuffed and wore t-shirts urging the release of their fathers.

There are more than 300 suspects held in Roumieh prison east of Beirut on terrorism-related charges, including members of the al-Qaida-inspired Fatah al-Islam group which fought the Lebanese army for more than three months last year.

Last week, the prisoners' families also staged a protest in front of the military tribunal in Beirut.
