TEHRAN, Nov. 19 (Xinhua) -- Iranian officials said on Tuesday that "foreign elements" were behind the blasts that targeted Iran' s embassy in Lebanon's capital Beirut in the morning.

In a telephone conversation with his Lebanese counterpart Michel Suleiman, Iranian President Hassan Rouhani said that the perpetrators of the blasts "were provoked by the extremists and foreign elements to destabilize the region and Lebanon."

"Such incidents cannot divide the Lebanese people and the officials," said Rouhani, adding that "the leaders of the country will secure the unity and stability of Lebanon with prudence."

Suleiman also condemned the blasts, saying that "the Lebanese government will do its utmost to arrest and punish the perpetrators."

According to Lebanon's National News Agency, a suicide bomber blew himself up in a parking lot near the Iranian embassy at 10:15 a.m. (0815 GMT) on Tuesday, followed by another suicide car bombing near the embassy.

A local security source estimated the weight of the explosive materials used in the explosion to be around 100 kg of TNT.

Lebanon's caretaker Health Minister Ali Hassan Khalil said some 146 were injured in the blasts and the death toll reached 23, adding that this number could increase. Later reports confirmed that the embassy's cultural attache, Ebrahim Ansari, was killed in the incident.

Iranian Foreign Ministry spokeswoman Marzieh Afkham strongly condemned the deadly blasts, calling them an "inhumane crime and spiteful measure by the Zionists (Israelis) and their mercenaries, " according to Iranian official news agency IRNA.

Since the blasts took place near Iran's embassy in Beirut, Iran 's foreign ministry is following up the case with "sensitivity and special care" and will provide further information about the incident to the public, Afkham told IRNA.

Meanwhile, Secretary of the Iran Supreme National Security Council Ali Shamkhani also slammed the attacks, describing them as a sign of desperation of Israel and its allies, according to Press TV.
