Let's take a look at what's going on in 'The World Now'.
In Cuba firefighters are battling a large fire at an oil depot.
The Cuban city of Matazanas is battling a blaze that started at an oil storage depot on Friday. The fire started when one of eight storage tanks at the facility was struck by lightning.
On Saturday, an explosion at a second storage tank injured over 100 people.
Reports say that one firefighter has been confirmed dead, 16 people are missing, and 24 have been hospitalized, with five in critical condition.
Meanwhile, Cuba has received help from Mexico and Venezuela, with both countries sending experienced firefighters and four planeloads of fire-fighting chemicals.
Each tank is capable of storing 300-thousand barrels of oil which is used for power plants.
The incident could worsen the current fuel shortage in Cuba.
Following elections held in June, Colombia is waking up to its first left wing president this morning.
This comes after Gustavo Petro, a former member of the M-19 guerrilla group, was sworn into office at the Bolivar Plaza in the capital of Bogota on Sunday.
The 62-year old former senator ran on a platform of social and economic reforms.
He has promised to fight hunger, and proposed a 5.8-billion-U.S.-dollar tax reform to fund social programs.
Petro has also pledged to revive negotiations with the remaining guerilla groups in the country.
Following his "rebound" infection, U.S. President Joe Biden has tested negative for COVID-19.
Biden left his White House isolation for the first time in two weeks on Sunday, after news of his test result on Saturday.
He initially caught the virus on July 21st, and began taking the anti-viral medication Paxlovid.
Biden then tested negative on July 26th and 27th, but was back in isolation on July 30th, after being hit with a "rebound" infection, a side effect associated with the COVID-19 medication. Despite his illness, the President continued working, giving occasional speeches from the White House Balcony.
The 79-year-old will head to Kentucky on Monday to meet those affected by the state's worst-ever flooding.
In the U.S. Lieutenant General Michael Langley has become the first African American to be promoted to the rank of four-star general in the Marine Corps.
Langley had been nominated by President Joe Biden in June and will now take charge of the U.S. Africa Command, from its base in Stuttgart, Germany.
Speaking during the promotion ceremony on Saturday, Langley spoke of the impact the milestone will have on younger people, and also payed tribute to those who had gone before him.
Up until 1942 black men were blocked from joining the Marine Corps.
The American military was then desegregated in 1948.
The first African American Marine was promoted to the rank of one-star general, in 1979.
