Well, I'm the .1%.
From "The Collapse of the Palestinian-Arab Middle Class in 1948: The Case of Qatamon", by Itamart Radai in Middle Eastern Studies,Vol. 43, No. 6, 961–982, November 2007:-
Exchanges of ﬁre between Qatamon and the adjacent Jewish neighbourhoods soon became commonplace. On the night of 2 January, Jewish Lehi blew up a number of abandoned buildings west of Qatamon. The explosions caused panic in the neighborhood, and in their wake ‘Abd al-Qadir al-Husayni, the commander of the irregular Arab forces in the Jerusalem area, paid his ﬁrst visit to Qatamon.According to some accounts, ‘Abd al-Qadir and his men met with the residents at the Hotel Semiramis, a small family establishment in the centre of the neighbourhood, and made plans to defend the area.36 [go left on Rehov Hahish, and descend to Rehov Mehalkei Hamayim.

The Haganah apparently got wind of the event through Shai, and this was one reason for the attack on the hotel on the night of 5 January. It was intended as retaliation against the Arabs for causing the ﬂight of Jews from Qatamon and other neighbourhoods.37
The Qatamon guard force received a report (perhaps a police warning) of an imminent attack on the neighbourhood. On the night of 5 January 1948 most of the force was sent to the neighbourhood’s northern boundary, opposite the Jewish neighbourhood Kiryat Shmuel, from where, they believed – rightly – the attack would originate. Seven guards were stationed on the roof of the Hotel Semiramis, which at three stories was one of the tallest buildings in the neighbourhood. However, the guards dispersed towards midnight due to a thunderstorm, believing that it ruled out the possibility of an attack that night. Shortly afterwards the Haganah force arrived at the hotel in two vehicles, blew it up, and withdrew without interference. The guards rushed out of their homes and opened ﬁre wildly, but to no effect.38
The explosion illuminated the sky above the neighbourhood for several minutes and shook the walls of houses hundreds of metres away. Frightened residents leaped out of bed and rushed to ﬁnd shelter in the bowels of their homes. Close to the site of the explosion some people went into shock.39
The hotel’s eastern wing collapsed; 18 people were killed and dozens wounded. Most of the dead were from two Arab Catholic families of Lorenzo and Abu Suwwan, the hotel’s co-owners. They had taken refuge in the hotel, believing it was safer than their homes in the Nikophoria Jewish-Arab neighbourhood.40

P.S. The Spanish vice-consul, Manuel Allende Salazar, was also killed in the attack.
And this following development preceded Deir Yassin by three months:
the explosion brought about the ﬁrst wave of departure from Qatamon, which included Arabs, Armenians, and Greeks. The deep shock and fear are reﬂected in the correspondence between Albina and the District Commissioner...
Oh, and unlike the Irgun, no warning was given.
