The Israeli government has refused to accept Syria's denials that it was implicated in the bombing of a nightclub in the Israeli city of Tel Aviv on Friday, when four Israelis were killed.
The Israeli Foreign Minister Silvan Shalom has summoned ambassadors from the European Union and the United Nations Security Council to a meeting tomorrow where he says military intelligence will provide proof of Syria's involvement.
The Syrian Foreign Minister, Faruq al-Shara, said he did not rule out the possibility Israel itself was behind the bombing in an attempt to undermine Palestinian national unity.
A cell of the militant group Islamic Jihad, based in the West bank said it carried out the attack. However, Islamic Jihad's leaders in Gaza have denied the group was behind the attack.
The Israeli Prime Minister, meanwhile, has said that Israel would step up operations against terror after the suicide bombing.
Ariel Sharon threatened to halt peace efforts with Palestinians unless they took vigorous action against militants. Mr Sharon was addressing his cabinet for the first time since the attack.
The Palestinian leader, Mahmoud Abbas, has vowed to punish those responsible.
It is also reported that Israel is to reconsider whether to free 400 Palestinian prisoners following the attack.
A radio station quoted Justice Minister Tsipi Livni as saying Israel may not release the prisoners that were to have been freed in addition to 500 released last week.
