JAKARTA, Indonesia (CNN) -- A tank in the Indonesian capital's sole fuel depot has caught fire, belching billowing black clouds of smoke into the air as millions of gallons of fuel blazed.
People watch a fire at Jakarta's lone fuel depot on Sunday.
Officials ordered nearby residents to evacuate and power cut to the immediate vicinity after the blaze began Sunday.
"A fuel tank in the depot containing 5,000 kiloliters of unleaded fuel has caught fire, the fire department is still trying to control the fire," said Anang R. Noor, spokesman for the state-owned gas company Pertamina.
He said the depot, the sole provider for the metropolitan area, has other tanks as well and contains a total of 50,000 to 60,000 kiloliters of fuel.
Jakartans lined up at area gas stations despite a statement from Pertamina that the capital had sufficient fuel reserves to last for a week.
Authorities were investigating the cause of the fire.
Last October, police in Indonesia arrested five suspected militants who they said were planning to attack the depot.
The suspected militants were believed to have ties to the al Qaeda-linked terrorist network, Jemaah Islamiyah, which aims to create a Muslim "superstate" across much of Southeast Asia.
Authorities blame Jemaah Islamiyah for the Bali nightclub bombings of 2002 that killed more than 200 tourists, most of them Westerners. Investigators also suspect the group in subsequent attacks in Jakarta on the Australian Embassy and J.W. Marriott Hotel.
