In the Indonesian capital, Jakarta, a mezzanine floor inside the tower of the stock exchange collapsed during lunch hour Monday.
People were evacuated from the building, and nearly 80 people were injured.
An employee of the World Bank in Jakarta, based in the same building, told the BBC a mezzanine walkway above the lobby had come down. He said he and members of his team were among those evacuated.
Most of the injured are reported to be college students from Palembang in Sumatra who were visiting the stock exchange as part of a study tour.
After the collapse, television footage showed the lobby littered with debris.
The Associated Press reports:
"National police spokesman Setyo Wasisto ruled out terrorism as a cause of the collapse.
" 'There is no bomb element in the incident,' he said.
"Figures released by five hospitals showed 77 people were injured."
The Wall Street Journal reports: "Indonesia Stock Exchange officials said the afternoon trading session would continue as normal following the routine 90-minute lunch break."
In the United States, the markets are closed Monday for the Martin Luther King Jr. holiday. They will reopen on Tuesday.
