12 killed after explosion hits bus carrying presidential guard members in Tunisia

At least twelve persons were killed and 20 others wounded on Tuesday after an explosion hit a bus carrying presidential guard members in Tunisia's capital, Tunis.

President Beji Caid Essebsi has declared a 30-day state of emergency and the capital is under curfew.

"They want to make us live with horror but we are going to bring that horror to the terrorist camps," Essebsi said in a televised speech. "We are at war and we are going to win."

The blast  happened at a bus stop where the presidential guard picks up and drops off its staff, near the former headquarters of the party of deposed President Zine El Abidine Ben Ali.

Authorities are investigating the event as a terror attack and no group has claimed responsibility for it.
