Anyway, while I was back in Qatar, something bad happened to my place too. This is what happened:
Apparently, someone tried to force entry into my apartment. Instead of trying to break the lock, they decided to cut off all the metals, climb in and break open the doorknob. There are marks on the doorknob showing someone tried to rip it off.
The landlord is planning to repair it, and then add another metal door on the inside of the house. That ought to fend off those who tried to break in, or at least frustrate them. I bet they wont suspect they have to go through 4 doors if they want to enter any of the rooms.
