ALGIERS - The United States embassy in Algeria has warned about a possible attack by a "terrorist group" on targets in Algiers, possibly near a US-branded hotel in the capital.

A statement on the embassy website told embassy employees to avoid hotels owned or operated by US companies on the July 4 US Independence Day and Algerian Independence Day on July 5.

The warning posted on Wednesday was one of several US security alerts about possible attacks by radical groups.
