Unknown assailants attacked Tuesday the headquarter of Derna Charity located in the Libya's port city of Derna with an explosive device but no casualties were reported, local source said.

The attack caused damage to the building and left nobody harmed, the source said.

Earlier, founder of Derna Charity Naser el Eker was assassinated by the Daesh terrorist group.

Libya plunged into chaos following the 2011 uprising against Muammar Gaddafi. The ouster of  Muammar Gaddafi gave rise to a patchwork of heavily-armed militias and deep political divisions.

The country has been witnessing numerous clashes between government forces and rival militia groups, which refuse to lay down arms.
