Wrong.
They were heavily armed Haganah.
They tried to shoot their way in with armored vehicles.
A medical team would have instead gone in with British or UN vehicles.
You simply are trying to pass false lies and propaganda.
There was no reason for a medical convoy to Jerusalem, when all the fighting was at the border, way west of the Jerusalem.

On February 22, 1948, three British Army trucks led by an armoured car driven by Arab irregulars and British deserters exploded on Ben Yehuda Street killing from 49 to 58 civilians
[1][2] and injuring from 140 to 200.
[3][4][5][6] The bomb may have been intended to kill members of the
Furmans (
Palmach convoy escorts) who lodged in the Atlantic and Amdursky Hotels but had left on patrol shortly beforehand.
[7] In addition to the two hotels, the Vilenchick Building and the Kupat-Milveh Bank were destroyed.
[7] The bomb had been created by Fawzi al-Qutb. The convoy was led by a Jerusalemite militant, 'Azmi al-Ja'uni, who spoke fluent English and could pass himself off as a British officer.
[4] Two British deserters, Eddie Brown, a police captain who claimed that the
Irgun had killed his brother, and Peter Madison, an army corporal, had been persuaded to join the attack, also by the promise of substantial financial rewards.

Why would British soldiers, (deserters or not), have blown themselves up in order to attack Jews in the Old Quarter?
Obviously it was fake.
It was likely ordered by David ben Gurion or Chaim Weizmann, in order to whip up war propaganda.
You either are very naive, or lying.
Arabs would not have attacked the Old Quarter because the majority of the residents of the Old Quarter are Arab.
