Prime Minister Benjamin Netanyahu warned Wednesday that Israel would strike a “resounding blow” if attacked by arch foe Iran, as regional tensions soar after the US killing of a top Iranian general.

“Anyone who attacks us will receive a resounding blow,” the premier told a Jerusalem conference after Iran launched a salvo of retaliatory missile strikes on bases used by US troops in Iraq.

“Qasem Soleimani was responsible for the deaths of countless innocent people, he destabilised many countries for decades, he sowed fear and misery and anguish and he was planning much worse,” Netanyahu said.

The Israeli premier praised US President Donald Trump for “acting swiftly, boldly, and resolutely” in killing Soleimani in the Iraqi capital Baghdad.The drone strike has put the United States and key allies on alert for Tehran’s response to the killing.
