Re: Saudi Arabia Shows Damd Aramco Site After Being Hit By Drones

basis of blaming Iran for Aramco strikes

Iran was blamed on basis of imry which showed remnants of country's missiles at Aramco sites, sources said.

level of sophistication of missiles clearly shows that missiles do t belong to Houthis, said experts. Britain too believes facts and points to Iranian involvement which British government has concluded is implausible without authorization by Iranian government. When reporters at New York asked wher UK will rule out military action and stick with Iran nuclear deal, Johnson said that UK too will be defending Saudi Arabia like US. When asked for assistance, UK will make itself useful, he ded. Pressed on wher this could mean Britain taking part in military action, he replied that all plans will be considered as per requirements.
