Sirens sounded in Tel Aviv on Sunday for the first time in months as Hamas' armed wing confirmed it launched a rocket attack on Israel's largest city.

Hamas' armed wing, the Al-Qassam Brigades, released a statement saying it had launched a rocket attack on Tel Aviv from Rafah.

"We bombed Tel Aviv with a large rocket barrage in response to the massacres against civilians," the statement said.

The Hamas fighters also posted an accompanying video showing what appeared to be rocket trails in the sky.

Israel Defense Forces said sirens sounded across central Israel Sunday after "eight projectiles were identified crossing from the area of Rafah into Israeli territory.

"A number of the projectiles were intercepted by the IDF Aerial Defense Array," the IDF statement said.

Israel's National Emergency Medical Service (MDA) said it received no reports of serious injuries.

"Following the Red Alert sirens heard in the center of the country: MDA teams did not locate casualties at any of the scenes, except for a patient who was lightly injured on the way to the protected space, and a number of victims with stress symptoms," the MDA said in a statement.

The IDF said later Sunday that it conducted an airstrike on the area where rocket launchers were used to direct rockets toward Tel Aviv, which the IDF said in a statement was "situated near two mosques in the area of Rafah."

Hamas has launched rocket attacks toward the areas around Gaza throughout the war but has not launched longer-range rockets in months. Sirens had not sounded in Tel Aviv in four months from Gaza-related rocket attacks.
