Dhaka, Nov. 27 -- The United States will bar entry to most travelers from eight southern African countries starting on Monday, after a potentially more-contagious new coronavirus variant was identified in South Africa, President Joe Biden said on Friday.

The new variant, dubbed Omicron, poses a new challenge for Biden, who has had a mixed success getting Americans vaccinated after a politically motivated pushback by 10 states. Biden also faces criticism from international health experts and foreign leaders for failing to send vaccines to poorer countries, reports Reuters.

The travel restrictions do not ban flights or apply to US citizens and lawful US permanent residents.

No cases of Omicron were identified in the United States to date...
