TRENTON — Declaring it New Jersey’s response to a national crisis, lawmakers on Thursday sent a half-dozen measures tightening the state’s already strict gun control laws to Gov.ernor Phil Murphy’s desk.

The Democratic-led Senate approved the bills that began advancing after a fatal high school shooting in Parkland, Fla., that left 17 people dead in February.

‘‘This is our response to our national crisis,’’ said state Senator Richard Codey. ‘‘We need national legislation.’’

Murphy has said he’s supportive of the measures as part of a campaign promise for what he called more sensible gun-control laws.

The legislation, previously approved by the Assembly, has seen a number of hearings, including an emotional meeting that featured mothers supporting tighter laws and National Rifle Association members who don’t. The measures have earned the scorn of gun rights advocates, who say they won’t protect people and only hurt law-abiding residents.

‘‘None of the bills passed today will make anyone safer,’’ said Scott Bach, executive director of the Association of New Jersey Rifle & Pistol Clubs. ‘‘Lawmakers have squandered an important opportunity to make our schools safer and prevent those with serious mental health issues from obtaining firearms in the first place.’’
