Israel is on high alert today after five Palestinian suicide attacks in 48 hours killed 12 people as well as the bombers.
Israeli police said today that earlier reports of an explosion in the coastal town of Netanya were false.
All police leave and training was cancelled, and thousands of police were deployed in town centres and about potential targets, including bus stations and shopping malls.
Military patrols were also stepped up along the borders with the Palestinian West Bank and Gaza Strip, which have been sealed since two bombers struck in east Jerusalem on Sunday.
But the clampdown failed to stop Hiba Darahmeh (19), an English literature student from the West Bank village of Tubas, from blowing herself up at a shopping mall in the northern Israeli town of Afula on Monday evening, killing three other people.
Thirteen of the 30 or so hurt in the blast were still in hospital today, and two were said to be in serious condition.
"The wave of attacks have not reached their peak and will continue," Israeli army radio quoted a senior defence official as saying.
The radio said Israel's Shin Beth intelligence service had failed to anticipate the attacks, even though the Israeli army has occupied the West Bank for the past year.
The first four attacks - one which killed two Jewish settlers in the West Bank, the two Jerusalem blasts and one in the Gaza Strip that wounded three soldiers - were claimed by the Islamic radical movement Hamas.
Its smaller rival, Islamic Jihad, and the Al-Aqsa Martyrs Brigade, an offshoot of Palestinian leader Mr Yasser Arafat's Fatah movement, jointly claimed responsibility for the Afula attack.
