Tesla CEO Elon Musk, known to stir up a storm with his tweets, sparked  another buzz today in a post talking about death under "mysterious  circumstances".

"If I die under mysterious circumstances, it's been nice knowin ya,"  tweeted Mr Musk, about a week after he announced his decision to buy  Twitter for $44 Billion.

Shortly before this, Musk shared a post that appears to be a  communication saying he is involved in "supplying the fascist forces in  Ukraine with military communication equipment".

"And for this, Elon, you will be held accountable like an adult - no matter how much you'll play the fool," the post adds.

The  communication also claimed that the equipment was delivered in Ukraine  by the Pentagon, headquarters of the US Department of Defense.

The two posts sparked speculation on whether the Tesla CEO is facing threats from Russia for helping Ukraine amid the war.

The tweet on death under mysterious circumstances met with varied responses, ranging from jokes to caution to solidarity.
