Saudi Arabia is pressing for a UN General Assembly vote Friday on a resolution condemning an alleged plot to assassinate its US envoy and calling on Iran to cooperate with the investigation.
The United States has said Iran was behind the plot to kill Riyadh's Washington ambassador, but the Saudi resolution, which was distributed at the 193 member assembly on Wednesday, did not directly accuse Iran of involvement.
The draft resolution "deplores" the plot and calls on Iran to "comply with all of its obligations under international law."
It says the Tehran government should "cooperate with states to bring to justice all those who participated in the planning, sponsoring, organization and attempted execution of the plot to assassinate the ambassador of the Kingdom of Saudi Arabia."
Saudi UN mission spokesman Abdulmohsen Alyas said many countries would co-sponsor the resolution but did not name them.
"Many countries understand our position and they agree with us by co-sponsoring this resolution," Alyas told AFP.
Iran has strongly denied involved in the alleged plot against the Saudi envoy, Adel al-Jubeir, possibly through the bombing of a Washington restaurant.
The United States has charged an Iranian-American car salesman over the plot and said Iranian officials planned to hire a Mexican drug cartel to kill the Saudi ambassador.
Iran's UN ambassador, Mohammad Khazaei, called the proposed resolution "dangerous" and "unacceptable" in a letter to UN leader Ban Ki-moon, according to Iranian media.
Iran's Foreign Minister Ali Akbar Salehi called on Saudi Arabia to delete references to "the recent US scenario" -- Iranian involvement in the plot, the state IRNA news agency said.
Mohamad Javad Larijani, a senior advisor to Iran's Supreme leader Ayatollah Ali Khamenei said Tuesday that the Saudi allegations are "a signal that American policy is falling apart" in the Middle East.
He said the Saudis feared the spread of Arab Spring uprisings to their own country.
"The wave of changes are reaching the Saudi border," Larijani told reporters at the UN where he is to make the Iranian case at votes on human rights resolutions.
Meanwhile, the Saudi-owned Al-Hayat newspaper reported that Saudi authorities have formed a security force to protect Saudi envoys abroad and foreign missions inside Saudi Arabia.
The kingdom's "general security body will supervise the team which will work under the umbrella of the interior ministry and is being armed at the highest levels," the London-based newspaper reported.
On Saturday, the Saudi embassy in Damascus came under attack by Syrian regime supporters who pelted the building with rocks before some people broke in.
Saudi Arabia was among 18 of the 22 members of the Arab League that voted on Saturday to suspend Syria from the pan-Arab bloc over the crackdown on opposition protests.
