Palestinian Authority security forces clashed with hundreds of Hamas supporters in the West Bank city of Hebron on Friday. Tear gas was used by the forces to disperse the crowd, which was advancing on an IDF checkpoint near the city, Israel Radio reported.

Earlier, demonstrators threw a firebomb at IDF troops manning a checkpoint near Hebron. The structure sustained damage but there were no injuries.

Hamas spokesman Fawzi Barhoum heavily condemned the Palestinian Authority security forces for breaking up the Hebron demonstration, calling the dispersal a “disgraceful and disrespectful” act designed to serve Israel, Ynet reported.

Violent clashes between Palestinian protesters and IDF forces also took place near Bethlehem, the Palestinian Ma’an News Agency reported.

Supporters of the Gaza-based terror group held a series of demonstrations across the West Bank in solidarity with the terror group and the people living in the coastal enclave.

According to Palestinian news channel Wattan, protesters were shouting slogans denouncing Egyptian President Abdel Fatah el-Sissi and the Egyptian stance in the conflict, accusing it of serving Israel. Other demonstrators, including children, were holding cardboard models of rockets.

On Monday, Israel’s Shin Bet security service claimed it had thwarted a Hamas coup attempt in the West Bank aimed at toppling Palestinian Authority President Mahmoud Abbas and starting a third intifada uprising.

The Shin Bet said it arrested more than 90 Hamas operatives in May and June, confiscated dozens of weapons that had been smuggled into the West Bank, and seized more than $170,000 aimed at funding attacks. It produced photos of the confiscated weapons and cash and a flowchart of the Hamas operatives who had been questioned, and said they planned a series of massive attacks on Israeli targets, including the Temple Mount, in order to start a widespread conflagration. Indictments are expected to be filed against at least 70 of the suspects.

Abbas said later Monday that the revelation was “a grave threat to the unity of the Palestinian people and its future.”
