Israel has struck back at Palestinian targets. Air force planes hit a workshop in Gaza city. Israeli commanders believe it was used to make rockets fired against Israeli territory. Palestinian officials said the attack caused damage but no casualties. The airstrike came after an Islamic Jihad suicide bomber killed nine people and wounded at least 40 others in Tel Aviv yesterday.Meanwhile Israeli security forces have carried out arrests on a main road inside Israel. Soldiers also moved into the West Bank town of Nablus and rounded up people they believe might be providing support to attacks against Israel. Police say the bomber, a 21 year old from near Jenin in the West Bank, was carrying at least 10 kilos of explosives. Investigators are trying to find out how he got to Tel Aviv’s old central bus station, in spite of a big security cordon deployed for the Passover holiday. Meanwhile the United States has denounced Hamas for not condemning the suicide attack. The White House said this revealed the true nature of the Palestinian government.
