The Netherlands: The public library and the zoo had some unusual visitors early Monday. Both were robbed.

Police said two thieves hit the ticket counter at the Artis Zoo shortly after it opened and stole an undisclosed amount of cash.

Earlier, around 2 a.m. (0100GMT), three masked and armed men overpowered the guards at a newly opened 13-story building housing the library’s main branch and other offices. Police declined to say what was taken.
