Tunisia

Tunisia's president says his country is "in a merciless war against terrorism." The victims reportedly include travelers from Japan, France, Poland, Italy, Colombia, Australia, Britain and Spain.

Tunisia's prime minister says at least 21 people — including 17 foreign tourists and two gunmen — died in the attack at the National Bardo Museum, a popular tourist attraction in Tunis.

A YouTube video shows a large group of men occupying a building that the U.S. ambassador to Libya says appears to be the embassy's residential annex.
