Turkish President Recep Tayyip Erdogan says parliament might consider a proposal to introduce the death penalty.
Mr Erdogan has accused a US-based Turkish cleric, Fethullah Gulen of being behind the plot, which Mr Gulen denies.
The attempted coup began on Friday night when a faction of the military took over key bridges in Istanbul and attacked parliament buildings in Ankara.
Thousands of people heeded Mr Erdogan's call to rise up against the coup-plotters, and by Saturday morning the rebel soldiers began to surrender their positions.
But a night of explosions, gunfire and clashes left 161 civilians and police dead, and more than 1,440 injured. The government said 104 'plotters' were killed.
High-level arrests
Major General Ozhan Ozbakir, commander of the Denizli garrison and the 11th Commando Bridgade, was among the senior military figures arrested on Sunday, Turkey's state-run Anadolu news agency reports.
Other top-ranking arrests include Gen Erdal Ozturk, commander of the Third Army; Gen Adem Huduti, commander of the Second Army; and Akin Ozturk, the former Chief of Air Staff.

Turkey has also requested the extradition from Greece of eight military officers who flew there in a Turkish military helicopter to claim political asylum as the coup began to unravel.
One of Turkey's most senior judges, Alparslan Altan, was taken into custody on Saturday. Some 44 judges and prosecutors were detained overnight in the central city of Konya and 92 in the south-eastern city of Gazientep, the private Dogan news agency reports.
'Harmful insinuations'
Mr Erdogan said that those behind the plot would pay a heavy price, calling the coup a "gift from God... because this will be a reason to cleanse our army".

He called on the US to extradite Mr Gulen.
US Secretary of State John Kerry said Turkey should "present us with any legitimate evidence that withstands scrutiny. And the United States will accept that and look at it and make judgements about it appropriately".
Mr Gulen has denied any involvement in the coup and said "as someone who suffered under multiple military coups during the past five decades, it is especially insulting to be accused of having any link to such an attempt".
The 75-year-old has been in self-imposed exile in Pennsylvania for the past 15 years, and said: "I don't even known who my followers [in Turkey] are."
Turkey's Labour Minister Suleyman Soylu suggested on Saturday that the US had been behind the coup - an allegations that received a strong rebuke from Mr Kerry.
"Public insinuations or claims about any role by the US in the failed coup attempt are utterly false and harmful to our bilateral relations," he reportedly told his Turkish counterpart by phone.
US President Barack Obama has joined other world leaders in calling for all parties in Turkey to "act within the rule of law".
Why did coup happen? - Jeremy Bowen, BBC News Middle East Editor
The attempted coup happened because Turkey is deeply divided over President Erdogan's project to transform the country and because of the contagion of violence from the war in Syria.
President Erdogan and his AK Party have become experts at winning elections, but there have always been doubts about his long-term commitment to democracy. He is a political Islamist who has rejected modern Turkey's secular heritage. Mr Erdogan has become increasingly authoritarian and is trying to turn himself into a strong executive president.
From the beginning Mr Erdogan's government has been deeply involved in the war in Syria, backing Islamist opposition to President Assad. But violence has spread across the border, helping to reignite the fight with the Kurdish PKK, and making Turkey a target for the jihadists who call themselves Islamic State.
That has caused a lot of disquiet. Turkey has faced increasing turmoil and the attempt to overthrow President Erdogan will not be the last of it.
– A militant group has warned the federal government to stop its double speak – It warned the oil production will be grounded in the country – MEND berated new militants for keeping quiet during Jonathan’s administration A militant group, the Ultimate Warriors of Niger Delta has issued a warning to the President Muhammadu Buhari-led federal government that if its demands are not met oil production in the country would become history. The Niger Delta region has become a hub for militancy and this and since President Buhari took over power, bombing of pipelines has escalated. READ ALSO: Minister reveals sponsors of Niger Delta Avengers The Ultimate Warriors of Niger Delta which is seen as an offshoot of the infamous Niger Delta Avengers that has claimed responsibility for series of bombings warned the federal government to stop the double speak instead of saying one thing and changing it afterwards. The group also warned the Movement for the Emancipation of the Niger Delta (MEND) to stop parading itself as the leader of militants in the region. “We have said it before that we have nothing to lose on the bombing of oil pipelines because our mission is to ground the oil economy if our demands are not met. We have said we are doing what we are doing to prod the government to renegotiate the control of our oil resources and other related matters. “We have watched with chagrin the recent utterance by the President (Muhammadu Buhari) and the Vice President (Yemi Osinbajo) and all we are see in them are double standard and lips service to the demand of the groups as its concerns the Niger Delta question and that is why all of our units and affiliates have not fully heeded to our ceasefire. Today, the president will say something, tomorrow his deputy and some of their dishonest and selfish lieutenants will contradict him and that only show how confused and unserious the government is about the problems and how to deal with them.” MEND however in its own statement urged the different militant groups to unite and speak with a common voice. The militant group expressed the need to speak through a single umbrella of the “Aaron Team 2 Dialogue and Peace Initiative” led by Mr. Odein Ajumogobia and berated mushroom militant groups who were silent during the administration of Goodluck Jonathan now coming out now.
