I started an accidental fire in friends apartment

Whle visiting a friend in their apartment rental, I accidentally started a fire in the oven while reheating food. Before I turned oven on I removed many pans,glass dishes and plastic containers that was stored inside oven and the friend said make sure I remove everything from oven. I did that but did not check the broile oven located below the oven of this gas type oven and later once fire started realized that too was full of plastic and wood containers. Unfortunately the smoke detector failed to go off and later found out that batter was missing in smoke detector. I would like to know who is liable for the damages, the friend who is the tenant, me who started the fire or the landlord who failed to have batteries in the smoke detector. Please note they just moved in a few weeks before the incident.
