Robert Mugabe, one of Africa's longest-serving leaders, has been sworn in for a new five-year term as Zimbabwean president.

The 89-year-old Mugabe was sworn in on Thursday during a ceremony held inside the 60,000-seat National Sports Stadium in Harare, the nation's capital, packed with tens of thousands of jubilant supporters.

According to the AP, Mugabe used the event to dismiss allegations of vote-rigging.

He said that Africa and many nations “hailed our elections as free and fair and credible” with the exception of “a few dishonest Western countries.”

“These Western countries hold a different negative view of the electoral process. Well, there's nothing we can do about their moral turpitude,” Mugabe said.

“We are not curtsying or bowing to any foreign government, however powerful it is or whatever filthy lucre it flaunts. We abide by the judgment of Africa. America dares raise a censorious voice to contradict Africa's verdict. Who gave them the gift of seeing better than all of us?”

Mugabe also reiterated his opposition to gay people.

“We hope you damn as much as we damn the doctrine that man can marry man and woman can marry a woman,” Mugabe said. “Let's not go against nature.”
