The Pittsburgh City Council on Tuesday approved new gun control legislation that will place restrictions on the use of military-style assault weapons, the Pittsburgh Post-Gazette reported. The legislation, introduced after last year’s mass shooting at an area synagogue, would make it illegal "to manufacture, sell, purchase, transport, carry, store or otherwise hold in one’s possession an assault weapon within the City," according to local NBC affiliate WPXI . The legislation will place restrictions on weapons like the AR-15 rifle, which authorities say was used in the Oct. 27 massacre at Tree of Life Synagogue that killed 11 and wounded several others. It would also ban armor-piercing ammunition and high-capacity magazines, as well as allow the temporary seizure of guns from people who are determined to be dangerous to themselves or others, the Post-Gazette reported. The measure, approved by a 6-3 vote, will now be sent to Mayor Bill Peduto (D) who is expected to sign it, according to the paper. The paper noted that the controversial legislation is expected to face court challenges from pro-gun advocates who say they’ll sue to block the laws from taking effect citing Pennsylvania state law that forbids municipalities from regulating guns.
