French MEP Rima Hassan from the far-left France Unbowed party was placed under police custody in Paris on Thursday. Hassan is being questioned and temporarily detained as part of an investigation into "apology for terrorism" over a social media post she wrote last week expressing solidarity with Japanese terrorist Kลzล Okamoto, according to reports first published by Le Parisien. Okamoto was convicted for a terrorist attack that killed 26 people at Ben Gurion International Airport in 1972. Her team argued that the temporary detention was a violation of the lawmaker's immunity as an MEP. A spokesperson for the European Parliament declined to comment "on ongoing procedures" but confirmed that "the Parliament is in contact with the national authorities, the member, and her political group." French far-right lawmaker Matthias Renault, who alerted French prosecutors to her post last week, was quick to react. "Finally, the beginning of the end of impunity for the France Unbowed lawmaker!" Renault wrote in a social media post on Thursday.
