A strong earthquake has struck Indonesia's Aceh province, killing three people and seriously injuring 25 others.
The quake, which briefly sparked a tsunami alert, measured 7.5 on the Richter Scale and had its epicentre around 300km from the Sumatra coast.
A 5.5-magnitude aftershock hit shortly afterwards, according to Indonesia's meteorological agency.
The Hawaii-based Pacific Tsunami Warning Centre said there was no threat of a 'destructive widespread tsunami' but that a local tsunami could affect coastal areas within a 100km radius.
Suharjono's meteorology office said that there were no immediate reports of damage from the quake.
Indonesia sits on the Pacific Ring of Fire where continental plates meet, causing frequent seismic and volcanic activity.
An earthquake-triggered tsunami in December 2004 killed some 168,000 people in Aceh, which is located at the northern tip of Sumatra.
Indonesia was the nation worst hit by the tsunami.
