Tears streamed down south Lebanon resident Fatima Hajj Ali's face as she stared at a host of keys hanging like wind chimes from the ceiling of a Beirut museum – each one symbolizing a home, like her own, destroyed by Israel.

"We were supposed to go home and open the door with the key, but there is no door anymore," the 23-year-old said.

The exhibition "Hkeeli ya Jnoub," or "Tell me, O South," features pictures and videos preserving the memory of southern Lebanon at the capital's Beit Beirut museum.

Walking through, Hajj Ali reminisced about her home in Nabatieh al-Fawqa, which she was only able to visit once after an April truce that ultimately failed to stop the fighting.

"Half the house collapsed and half remained," she told Agence France-Presse (AFP).
