DUBAI - Iran's supreme leader Ayatollah Ali Khamenei on Tuesday called Israel a "rabid dog" for its attacks targeting Hamas in Gaza, and urged Muslims to arm Palestinians to enable them to counter what he termed genocide.
In a speech marking the end of the Muslim fasting month of Ramadan, Khamenei criticized the United States and European countries for what he said were their efforts to limit the military capacity of Palestinian fighters in the enclave.
Of Israel, he said: "This rabid dog, this rapacious wolf, has attacked innocent people and humanity must show a reaction. This is genocide, a catastrophe of historical scale."
"They have been pounding innocent people day and night and these men, women and children are defending themselves with minimum means, and now Americans and Europeans want to take even that away ... so that those merciless beasts could pound without qualm."
Khamenei denounced what he said was a ruling by US President Barack Obama to disarm Palestinians - an apparent reference to US opposition to efforts by Hamas, the Islamist terror group that controls Gaza, to obtain weapons such as missiles and rockets. Washington views Hamas as a terrorist organization.
Khamenei said Iran took the opposite view about arming Palestinians.
"Everyone, whoever has the means, especially in the Islamic world, they should do what they can to arm the Palestinian nation ... the Zionist regime deeply regrets starting this (war) but has no way out."
Israel launched its offensive on July 8 with the aim of halting rocket attacks by Hamas and its allies. It later ordered a land invasion to find and destroy the warren of Hamas tunnels that criss-crosses the border area.
About 1,087 Gazans are said to have been killed in 22 days of fighting between Israel and Palestinian militants in the Gaza Strip. As well as 53 Israeli soldiers killed, three civilians have died as a result of Palestinian shelling.
Tehran is at loggerheads with Western powers on a range of foreign policy issues including its nuclear program and its support for Hamas, Syria's President Bashar Assad and the Lebanese Shi'ite militant movement Hezbollah.
Khamenei's speech to a crowd of hundreds of thousands in Tehran was broadcast live on state television. Khamenei was accompanied by senior government officials.
