At least one of the bombs bore a note, in Arabic and Hebrew, that stated “revenge from the Tulkarem refugee camp,” a reference to the terrorist hotbed where security forces have been conducting operations, Channel 12 News reported.

Five explosive devices, all with timers set to go off simultaneously, were found in what was intended to be a “strategic terrorist attack,” per Channel 12, which cited security sources.

Israel Katz, the Israeli defense minister, directed the Israel Defense Forces to increase “the intensity of activities to thwart terrorism in the Tulkarm refugee camp and in the refugee camps in Judea and Samaria in general” following what he called “serious terrorist attacks attempted” in the Tel Aviv area on Thursday night.

“We will pursue the terrorists to the bitter end and destroy the terrorist infrastructure in the camps that serve as a frontline for the Iranian axis of evil,” Katz stated.

“Palestinian terrorists were planning a massive attack tomorrow morning,” stated David Friedman, a former U.S. ambassador to Israel. “Bombs have been identified on multiple buses and other public transportation that were to be detonated during the morning rush hour.”

“The casualties could have been overwhelming,” Friedman wrote. “Thank God this attack was stopped, and may all these terrorists be wiped from the earth before they can kill again.”

The Israel Security Agency (Shin Bet) was reportedly called to the scenes, and all bus drivers in the Tel Aviv metropolitan area have been instructed to search their vehicles for possible explosive devices.

Miri Regev, the Israeli transportation minister, instructed the National Public Transport Authority to “stop and inspect all buses, heavy trains and light rails and act in accordance with the instructions of the Shin Bet and the police.”

“The incident began at two locations just minutes apart. Two bombs were detonated on two buses that were empty,” Zvika Brot, the mayor of Bat Yam, told local media. He added that “there are suspicions of an additional bomb.”

Shortly after Brot issued his statement, Israeli media outlets aired video footage of what was said to be a third bus explosion in the Bat Yam area.

The devices were “likely meant to detonate during rush hour for a mass casualty attack,” wrote Mark Dubowitz, CEO of the Foundation for Defense of Democracies.

“These multiple bus bombs in Israel are suspected of being planted and set to detonate tomorrow morning as commuters would be headed to work,” wrote Jason Brodsky, policy director at United Against Nuclear Iran. “Worth noting the head of Palestinian Islamic Jihad has been visiting Iran this week.”
