Bangladesh Nobel winner Muhammad Yunus has said he is ready to head a caretaker government, a day after the military took control as mass protests forced longtime ruler Sheikh Hasina to flee.
Microfinance pioneer Yunus, 84, is credited with lifting millions out of poverty, earning the enmity of ousted Hasina and the wide respect of millions of Bangladeshis.
"If action is needed in Bangladesh, for my country and for the courage of my people, then I will take it," he said in a statement, also calling for "free elections", after student leaders called for him to lead an interim government.
Ms Hasina, 76, had been in power since 2009 but was accused of rigging elections in January and then watched millions of people take to the streets over the past month demanding she quit.
Hundreds of people were killed as security forces sought to quell the unrest but the protests grew and Ms Hasina finally fled aboard a helicopter yesterday after the military turned against her.
Army chief General Waker-Uz-Zaman announced the military would form an interim government, saying it was "time to stop the violence".
The president dissolved parliament, a key demand of the student leaders and the major opposition Bangladesh National Party (BNP), which has demanded elections within three months.
"In Dr Yunus, we trust," Asif Mahmud, a key leader of the Students Against Discrimination (SAD) group, wrote on Facebook.

The military reshuffled several top generals, demoting some seen as close to Ms Hasina, and sacking Ziaul Ahsan, a commander of the feared and US-sanctioned Rapid Action Battalion paramilitary force.
Ex-prime minister and BNP chairperson Khaleda Zia, 78, was also released from years of house arrest, a presidential statement and her party said.
Streets in the capital were largely peaceful, with traffic resuming, shops opening and international flights resuming at Dhaka's airport, but government offices were mainly closed a day after chaotic violence in which at least 122 people were killed.
Millions of Bangladeshis flooded the streets of Dhaka to celebrate after General Waker's announcement and jubilant crowds also stormed and looted Ms Hasina's official residence.
"We have been freed from a dictatorship", said Sazid Ahnaf, 21, comparing the events to the independence war that split the nation from Pakistan more than five decades ago.
Police said mobs had launched revenge attacks on Ms Hasina's allies and their own officers, as well as broke into a prison, releasing more than 500 inmates.
Yesterday was the deadliest day since protests began in early July, with a further ten people killed yesterday, taking the total toll overall to at least 432, according to an AFP tally based on police, government officials and doctors at hospitals.
Protesters broke into parliament and torched TV stations. Others smashed statues of Ms Hasina's father, Sheikh Mujibur Rahman, Bangladesh's independence hero.

Some businesses and homes owned by Hindus, group seen by some in the Muslim-majority nation as close to Ms Hasina, were also attacked, witnesses said.
Bangladeshi rights groups, as well as US and European Union diplomats, said they were "very concerned" about reports of attacks on religious, ethnic and other minority groups.
Key police unions said their members had declared a strike "until the security of every member of the police is secured", offering their "apology" for police actions against the protesters.
Key regional allies of Bangladesh, neighbouring India and China, both called for calm.
China hopes that "social stability can be restored in Bangladesh" soon, the foreign ministry in Beijing said, while Indian foreign minister S Jaishankar said he was "deeply concerned till law and order is visibly restored".
The unrest began last month with protests against civil service job quotas and escalated into wider calls for Ms Hasina to stand down.
Her government was accused by rights groups of misusing state institutions to entrench its hold on power and stamp out dissent, including through the extrajudicial killing of opposition activists.
Mothers of some of the hundreds of political prisoners secretly jailed under Hasina's rule waited outside a military intelligence building in Dhaka.
"We need answers," said campaigner Sanjida Islam Tulee.
The fate of Ms Hasina, now in India, is also uncertain.
A source had said she wanted to go to London but calls by the British government for a UN-led investigation into the "unprecedented" violence put that in doubt.
Thomas Kean from the International Crisis Group said the new authorities faced a daunting challenge.
"The interim government that will now assume power...needs to embark on the long task of rebuilding democracy in Bangladesh, which has been so badly eroded in recent years," he said.
