Are German IHH and Turkish IHH related?

Today we saw many news stories about the German government banning the IHH - the Internationale Humanitäre Hilfsorganisation - "charity" organization because of its ties with Hamas: Germany's government has banned an organization it accuses of collecting donations that are sent to Hamas-related welfare projects. The Islamist movement is included on the European Union's terror group blacklist. German Interior Minister Thomas de Maiziere said in a statement that the International Humanitarian Relief Organization was banned Monday because it has used donations to support projects in Gaza that are related to Hamas – while presenting their activities to donors as humanitarian help.
