Turkey's Parliament passed a law that increased monitoring of foundations and associations and, human rights groups say, could limit the freedom of society.
The law allows the interior minister to replace members of organisations who are under investigation for terrorism charges, while the Interior Ministry can apply to courts to halt the groups' activities.
International organisations will also be included under the law and can be penalised accordingly.
Parliament approved the bill – drafted by President Recep Tayyip Erdogan's AK Party, which holds a majority with its nationalist MHP allies – on Sunday, the assembly said on Twitter.
This week seven organisations, including Human Rights Association and Amnesty International, said terrorism charges in Turkey were arbitrary, and that the law goes against the presumption of innocence and punishes those whose trials are not finalised.
"Given that thousands of civil society activists, journalists, politicians, members of professional organisations are investigated within the scope of [anti-terrorism law], there is no doubt that this law will target almost all opponent associations," they said.
Investigations based on terrorism charges have been launched against hundreds of thousands of people after a failed coup in 2016.
Members of Amnesty and other groups have been investigated and tried, while hundreds of foundations were shut down with decrees.
Critics said Mr Erdogan's government has used the coup attempt as a pretext to quash dissent.
The government said the measures were necessary given the security threats facing Turkey.
Under the law, foundations will be inspected annually by civil servants.
Local governors or the interior minister can block online donation campaigns using a measure to prevent terrorism financing and money laundering.
Fines of up to 200,000 lira ($26,500) can be levied, compared to a previous maximum of 700 lira, in a move the seven organisations said will "in practice lead to the closure of many associations".
