CAIRO — Egyptian opposition figures said Wednesday that assailants attacked a Ramadan party they hosted in Cairo, pelting them with plates and water bottles while chanting ‘‘Long live Egypt!’’ the slogan of supporters of President Abdel Fattah el-Sissi.

The outdoor iftar, a feast marking the end of the daily dawn-to-dusk fast during the holy month, was hosted by the Civil Democratic Movement, a coalition of secular and left-leaning parties that had called for a boycott of Egypt’s March presidential election. El-Sissi won a second term after several potentially strong candidates were arrested or pressured into withdrawing.

Members of the opposition group posted pictures online showing overturned tables and food strewn across the ground.

Rights activists say Egyptian authorities have a long history of recruiting plainclothes thugs to attack protesters and opposition figures.
