Police in Indonesia have released sketches of two men they believe are responsible for bombing two luxury hotels in Jakarta last week, killing nine people, including themselves.

Sketches of the two men were released to the public on Wednesday and was based on two bodies found among the rubble at the J.W. Marriott and Ritz-Carlton hotels.

Police said that the suspect found at the Ritz was likely between 20 and 40 years old with dark skin and short, dark hair. The other suspect, who was found at the Marriott, was likely about 16 or 17 years old with lighter-coloured skin.

The attack happened Friday morning when two men posing as guests detonated a bomb at the hotels.

Two Canadians were among the injured as well as three Australians -- one of whom is the first diplomat from that country to be killed in a terrorist attack.

Police stopped short of naming suspects, though terrorism experts and investigators have said they believe Jemaah Islamiyah -- a Southeast Asian terrorist group -- is to blame. The group and its violent offshoots have carried out several attacks with the support of al Qaeda between 2002 and 2005.

Counterterrorism experts say explosives found at the bombing scene are "identical" to those used in previous attacks.

Local news reports out of Indonesia on Wednesday said that police had detained the wife of one of Southeast Asia's most-wanted militants.

Ariana Rahma, who is married to Malaysian fugitive Noordin Mohammad Top, was taken in for questioning by anti-terrorism police, according to TVOne and MetroTV.

The broadcasts did not cite the source of their information.

Authorities are expected to bring her to Jakarta.

Her husband has been part of Jemaah Islamiyah in 1998 after training in the southern Philippines.

Police have been looking for the man for several years but he has eluded being captured several times. Authorities allege Noordin is responsible for the 2002 and 2005 bombings in Bali as well as the attacks on the Marriott and Australian Embassy in 2003 and 2004.

More than 240 people were killed in those attacks.

Malaysian police have questioned three Noordin supporters about Friday's bombings in Jakarta.
