US Marine Corps General Kenneth F. McKenzie Jr., Commander of the US Central Command (CENTCOM), poses for a picture during his visit to a military base in al-Kharj in central Saudi Arabia on July 18, 2019. - McKenzie pledged on July 18 to work "aggressively" to ensure maritime safety in strategic Gulf waters after a spate of attacks blamed on Iran. McKenzie's visit to Saudi Arabia comes a day after the US House voted to block $8.1 billion in arms sales to the kingdom and other allies, in a move likely to be vetoed by President Donald Trump.
