As the number of victims continues to climb in Gaza, a crowd of more than 1,500 people rallied in Tokyo on Saturday to call for an immediate ceasefire in the war-torn area.

Despite the chilly and windy weather, the rally, organized by various nonprofit and nongovernmental organizations, attracted about 1,500 people, organizers said.

"We cannot definitely tolerate the indiscriminate attacks. Whether it's Israeli or Hamas, we cannot put up with an attack that involves regular civilians," Sonoko Kawakami of Amnesty International Japan told the participants at the foot of Tokyo Tower in Minato Ward.
