Tens of thousands of demonstrators in central London participated in a solidarity march for Gaza on Saturday as fighting between the IDF and terrorists in the enclave resumed after a 72-hour cease-fire ended Friday morning. Also on Saturday, tens of thousands of people rallied in Cape Town against the IDF's renewed operations in Gaza amid fresh salvos of rocket attacks launched from the Strip following Hamas's refusal to extend a temporary cease-fire with Israel.At the rally in the South African city, Nobel laureate Desmond Tutu accused Israel of behaving like a "barbaric bully" in Gaza.In Yemen, demonstrators also marched in the country's capital city of Sanaa in solidarity with Gaza while condemning Israel and calling on Egypt to open its border crossing with the Gaza Strip."We took to the streets in order to show our solidarity for our brothers in Gaza who are blockaded and abused by the Zionists in collaboration with our Arab brothers. Our message today for Arab regimes, especially our brothers in Egypt, is open the Gaza crossing," said protester Abuldrahman al-Selwi. The IDF has conducted more than 30 airstrikes since midnight, including on launching pads, command and control centers and other terror sites. Since early Saturday, Palestinian terrorists have launched 28 rockets towards southern Israel, according to the IDF.
