The United States is extending restrictions on non-essential travel at land and ferry border crossings until Sept. 21.
The U.S. Department of Homeland Security says in a tweet the measures are being kept in effect to reduce the spread of COVID-19, including the Delta variant.
It says it will keep ensuring "the flow of essential trade and travel" and keep working with health and medical experts, as well as international partners, to figure out when things can safely return to normal.
The restrictions, which have been in place since March 2020, were set to expire Saturday.
