Iranian people accorded respect to the memory of the martyrs by lighting candles and laying wreaths at the stations, according to a Farsi report by ISNA.
Many people also flocked to blood transfusion centres to donate their blood following the incident.
Morteza Tabatabaei, the director general of Tehran Blood Transfusion Centre, said 2,800 Tehrani citizens have volunteered for blood donation at the city’s blood transfusion centres over the past two days (Thursday and Friday), of which 2,300 have managed to donate their blood.
People’s move was aimed at helping save those who have been injured in the tragic incident.
The high-rise building caught fire on early Thursday and came down only hours later, blockading 25 to 30 people under the rubble.
As many as 200 firefighters had been deployed to the site to put out the fire.
The building was one of the Iranian capital’s oldest high-rises, which was housing 600 production workshops, 400 of which were being used for making shirts.
The damage from the collapse is estimated to stand at around $463 million.
