I had forgotten about the Muammar brothers.
FWIW here is what Wiki says.

An Israeli spokesman confirmed the detentions, said that both men were members of the militant group Hamas intending to carry out imminent attacks on Israel and stated "These Palestinians were transferred to Israel where they will be questioned".[3][2] A spokesman for Hamas confirmed that the brothers were sons of a member but denied that the men detained were involved in Hamas.[2][3]

This event was followed by capture of Israeli soldier Gilad Shalit on June 25, 2006 and further incidents in the 2006 Israel-Gaza conflict.

This is claimed by Noam Chomsky[4] and Jonathan Cook for the Media Lens website[5] to be the first incident in the 2006 Israel-Gaza conflict and the following 2006 Israel-Lebanon conflict.
