The spokeswoman, speaking from the Australian capital, Canberra, had no details on when the team would arrive in Israel. She spoke on customary condition of anonymity.

Israel's Mossad spy agency is widely suspected of carrying out the Jan. 19 slaying of Mahmoud Al-Mabhouh in a luxury Dubai hotel, but Israel has neither confirmed nor denied involvement. Israel claims Al-Mabhouh was a major player in smuggling weapons to Hamas militants who control the Gaza Strip and attacked Israel with bombs, rockets and mortars for years.

Last week, the Australian government summoned the Israeli ambassador, Yuval Rotem, for an Israeli explanation of the passport scandal. Afterward, Prime Minister Kevin Rudd pronounced himself "not satisfied" with the Israeli government's answer to "the use and abuse" of Australian passports.

"We still have a way to go yet with the Israeli government on the matter," Rudd said.

Dubai police say 26 suspects used fake British, Irish, French and Australian passports of real people in the assassination. At least 15 of the suspects share names with Israeli citizens, who say they were victims of identity theft and deny having been in Dubai.

Britain has already sent a special police investigator to Israel to meet with eight dual nationals whose passports were used in the slaying.

Dubai police say they are convinced that Israel assassinated Al-Mabhouh, who was also wanted in the 1989 killing of two Israeli soldiers. They contend Al-Mahbouh's assassins used a powerful muscle relaxant to incapacitate him before suffocating him with a pillow in his hotel room.

On Monday, Dubai police announced that dual-national Israelis arriving on foreign passports would be barred from entering. Voice and face profiling will be used to detect Israeli citizens.

In Beirut, a Hezbollah lawmaker said Tuesday security must be stepped up for all foreigners entering Lebanon as they could be secret agents like those who murdered the Hamas commander in Dubai.

"We must tighten foreign passport control at the airport and elsewhere in the country," Hezbollah MP Nawaf Moussawi said.

"Every Lebanese and Arab must deal with holders of foreign passports as potential spies."

Moussawi slammed European states for failing to "assume responsibility for the violation of their sovereignty" over the use of their passports by Mabhouh's killers in Dubai.

"If European countries do not respect their own passport-holders... then they must expect they will be treated with suspicion," he said.

Moussawi said Israeli journalists with EU passports had also entered Lebanon in 2006 during Hezbollah’s devastating war with the Zionist state.

"It happened in Lebanon in 2006, so the risk of it happening again is more than likely," said the MP.

Lebanese authorities have made dozens of arrests in an expanding crackdown on Israeli espionage rings launched last year.

Lebanon and Israel remain technically at a state of war, and convicted spies face life in prison with hard labor or the death penalty if found guilty of contributing to Lebanese loss of life.

Hezbollah chief Hassan Nasrallah on Monday called for any Lebanese citizens convicted of spying for Israel in a series of trials in recent months to be hanged.
