A sister of Hamas leader Ismail Haniyeh has been arrested on suspicion of contact with operatives from the terror group and supporting acts of terror, defense sources say.

Police say that they arrested the 57-year-old woman in a joint raid with the Shin Bet.

The suspect, who is not identified by police in the statement, is a resident of the southern town Tel Sheva.

In a statement, police say that during a raid on the suspect’s home, officers found documents, media, telephones and other evidence linking her to “serious security offenses.”

The woman will appear at the Beersheba Magistrate’s Court later today for a hearing on her detention.
