German Foreign Minsiter Sigmar Gabriel's wife is receiving threats after Turkish President Recep Tayyip Erdogan lashed out at the minister, warning him to "know his limits'', Sputnik News reports, referring to the Rheinpfalz newspaper.
Earlier, Gabriel called on Ankara to abstain from meddling in the country's general elections after which Erdogan made harsh statements against the minister.
On Sunday night unknown people had left messages with threats on an answering machine in a dentist clinic where the minister's wife works.
"The way Erdogan does this [criticizes the minister] motivates some people to try to harass and bother my wife… When a head of state starts to act against an individual, unfortunately there are people who think they have the right to organize oppression of this individual," Gabriel was quoted as saying by the Welt newspaper.
