The US joining Israeli strikes would cause "hell for the whole region", Iran's deputy foreign minister said, BBC reported.

Saeed Khatibzadeh said this is "not America's war" and if US President Donald Trump does get involved, he will always be remembered as "a president who entered a war he doesn't belong in".

He said US involvement would turn the conflict into a "quagmire", continue aggression and delay an end to the "brutal atrocities". 

His comments came after the Soroka hospital in southern Israel was hit during an Iranian missile attack. Iranian state media reported that the strike targeted a military site next to the hospital, and not the facility itself, according to BBC.
