Israeli Prime Minister, Benjamin Netanyahu on Thursday mandated the military to conduct an intensive operation in the West Bank after explosions on buses close to Tel Aviv.
Although no casualties were reported, the office of the prime minister described the incident as an attempted mass attack.
The Israeli police earlier said there had been explosions on three buses in two Israeli suburbs outside Tel Aviv, stressing that four explosive devices had been found.
According to local media, the explosions had occurred on buses in depots and were empty.
The explosions were a stark reminder of the devastating bus bombings in Israel that were a hallmark of the Palestinian uprising of the 2000s, although such attacks are now rare.
In a statement, the military said it was assisting the police and Shin Bet intelligence agency in the investigation.
The police also said it was searching for suspects, urging the public to remain vigilant.
