New York City Mayor Bill de Blasio (dih BLAH'-zee-oh) has made a trip to Paris to show his support after terrorist attacks there left 17 people dead.

De Blasio paid his respects Tuesday at the offices of the Charlie Hebdo satirical newspaper and at a kosher supermarket. The attacks were carried out Jan. 7 and 9.

De Blasio was accompanied by Paris Mayor Anne Hidalgo and Charlie Hebdo columnist Patrick Pelloux. He laid flowers at a memorial up the street from the newspaper's office.

De Blasio says the trip is to show New York's solidarity with Paris as cities that have dealt with terrorism.

He says there's a powerful historical similarity between the cities. He says the tragedies have shown they're even closer than people realized.
