Officials say two lions have escaped from a zoo in eastern Germany.

The Leipzig Zoo told the dpa news agency Thursday that the lions somehow escaped from their cages overnight and are somewhere on the zoo grounds.

The zoo's not opening to the public until the two cats are found, and the zoo says an emergency plan is in place.

The two male lions, Majo and Motshegetsi, were born about a year ago in the Basel Zoo and have been at the Leipzig Zoo since August.
