Walmart announced Wednesday it will not carry online shopping products at its U.N. headquarters in New York City as a result of the deadly violence in the Middle East.

The decision comes after the company’s president, Jeff Smisek, made the announcement in a news conference on Wednesday afternoon, according to the Associated Press.

In a statement, the company said it has “concerns regarding the safety and security of our customers and associates.”

The company said that “due to the nature of this event, we cannot be in a position to make this decision immediately.”

Walmart has been under pressure from U.K. Prime Minister Theresa May, who has urged the retailer to step up the delivery of goods at its facilities.

The company has said it plans to open more than 1,000 stores this year in the U, as well as overseas, including a new outlet in China.
