"The parade made Sunday a sad day for Israelis," Hamas spokesman Sami Abu Zuhri said.
"It proved that Netanyahu had failed in undermining Hamas," he added in a statement.
The brigades staged an elaborate military parade in Gaza City earlier on Sunday to commemorate the 27th anniversary of the founding of Hamas.
Hundreds of masked brigade members marched through Gaza's main roads, holding locally-manufactured and other rifles as well as mortar shells.
The fighters also demonstrated, for the first time, one of three locally-manufactured drones.
They also paraded two domestically-produced M75 and R160 rockets, used in striking Israeli cities during this summer's Israeli military offensive on the blockaded coastal enclave.
Hamas fired hundreds of rockets at Israeli cities during Israel's 51-day military onslaught on the coastal strip in July and August.
The Israeli military operation, launched with the stated aim of ending rocket fire from Gaza, left 2,160 Palestinians dead and more than 11,000 injured, the vast majority of them civilians.
Around 73 Israelis – including 68 army troops – were also killed over the same period, according to Israeli data, while a total of 2,522 Israelis, including 740 troops, were reportedly injured during the conflict.
