At least Three people were killed and eighteen wounded on Thursday after two explosions rocked the Geha bridge area on Jabotinsky street near Tel Aviv at 18:20.

Channel Two reported that two of the victims were women, and their bodies were taken to Abu Kabir Forensic Institute.

The blast took place at a busy bus stop under the Geha Bridge - a major junction just outside Tel Aviv used by commuters to reach Tel Aviv, Petah Tikva and Bnei Brak.

Following the attack, Defense Minister Shaul Mofaz ordered the IDF to impose a full closure on the territories, and said he would have to reconsider the recent concessions granted to the Palestinian population.

Magen David Adom officials reported that four people were seriously injured in the blast which took place underneath the Geha Bridge. The wounded have been taken to Tel Hashomer, Beilinson hospitals.

Speaking from the scene of the attack, Police Insp.-Gen. Shlomo Aharonishky said that there was not a specific warning of a terror attack in the Bnei Berak area and that the explosive device was of medium size.

"After three months without a terror attack within the Green Line there were many foiled attempts but the situation is still volatile and today’s attack shows that on the other side there is no strategic change," Aharonishky said.

Witnesses said the wounded still left at the scene are not seriously wounded.

Police officials estimated that the blast was a terror attack - possible carried out by a suicide bomber. Police have closed the area and are conducting searches. A helicopter has joined the search.

Yossi Sedbon, Tel Aviv district police commander told Israel’s Channel 2 television. "We believe that this was a terror attack." Sedbon said that one suicide bomber was involved in the attack and not two bombs as previously thought.

He mentioned that several months ago at the scene of the attack TA police captured over 100 Palestinian illegally residing in Israel who were living in bushed nearby the bus station and added police would have top investigate if there was a connection.

Police said there were no specific warnings of attacks in the area. Security sources said there was no connection between the pepetrators of the attack to those nabbed two weeks ago who planned to attack Ramat Gan.

Director of Sheba Hospital Zev Rotshtein said that doctors there were primarily working on two youths, one female and a male, who had suffered serious shrapnel wounds to the bottom part of their bodies.

Witnesses said an explosion blew out windows in the area. The witness said he did not see a bombed out bus.

Police are asking the public to stay away from the area so as to let the evacuation of the wounded take place.

The attack, if a suicide bombing, would be the first since an Oct. 4 bombing at a restaurant in the northern Israeli city of Haifa that killed 21 people.
