sit-in

先程と同じニュースから表現を拾います。

People have been protesting what they describe as the "authoritarian" attitude of the government and the heavy-handed way in which the police dealt with a peaceful sit-in in Gezi Park, next to Taksim. Mr Erdogan's government wants to redevelop the park to build a shopping centre. The confrontation between mostly peaceful protesters and the riot police became almost a pitched battle late on Friday and went on until late on Saturday, when the police finally withdrew from Taksim.

sit-inに注目しました。文中では「座り込み抗議」（『ジーニアス英和辞典　第３版』大修館）という意味になります。念のため英英辞典を見てみると’a form of protest in which demonstrators occupy a place, refusing to leave until their demands are met’ODOと記載されていました。

余談ですが、自動詞のsit inの場合は「｛競技・会議などに｝参加する[at,with];｛討論などを｝参観[傍聴]する[on]」（ibid）という意味の他に「（デモで）座り込む」（ibid）という語義もあるので、併せて覚えておこうと思います。(Shou-VR*)
