DUBAI,
 Aug 5 (Reuters) - Iran is not looking to escalate regional tensions but
 believes it needs to punish Israel to prevent further instability, the 
foreign ministry spokesperson said on Monday, following the 
killing of Hamas leader Ismail Haniyeh in Tehran last week.
"Iran
 seeks to establish stability in the region, but this will only come 
with punishing the aggressor and creating deterrence against the 
adventurism of the Zionist regime (Israel)," Nasser Kanaani said, adding
 that action from Tehran was inevitable.
Kanaani
 called on the United States to stop supporting Israel, saying the 
international community had failed in its duty to safeguard stability in
 the region and should support the "punishment of the aggressor."
Iran's
 foreign ministry called in ambassadors and heads of missions residing 
in Tehran for a meeting with acting Foreign Minister Ali Bagheri Kani on
 Monday to reiterate Iran's will to respond to Israel.
An
 emergency meeting of the Organisation of Islamic Cooperation will be 
held on Wednesday at Iran's request to discuss the killing of Haniyeh 
and Iran's response, said Kanaani.
Tehran and Iran-aligned groups such as Hamas and Hezbollah have accused Israel of 
killing Haniyeh
 on July 31 in the Iranian capital. His death was one in a series of 
killings of senior Hamas figures as the war in Gaza between Hamas and 
Israel nears its 11th month.
Israeli officials have not claimed responsibility.
The
 Islamic Revolutionary Guards Corps' top Commander Hossein Salami on 
Monday repeated the elite group's threat that Israel "will receive 
punishment in due time".
