CAIRO — Egypt’s president, Abdel-Fattah el-Sissi, on Monday ratified a law that heavily restricts the registration and work of charities, rights groups, and other nongovernmental organizations.

The law gives security agencies extensive power over the financing and activities of such groups.

International rights activists described the law as Draconian and a ‘‘death warrant’’ to rights groups, saying it would effectively lead to the shutdown of many groups.

The law comes as part of Sissi’s wider crackdown on dissent since he rose to power in 2013, when he led a military overthrow of his Islamist predecessor Mohamed Morsi.

The new law limits the activity of nongovernmental groups to development and social work and provides jail terms of up to five years for noncompliance.

Supporters believe that the law is necessary to regulate foreign-funded groups accused of feeding political chaos starting from the 2011 uprising that led to the ouster of longtime president Hosni Mubarak.

Activists say the crackdown under Sissi has mostly erased democratic freedoms won in the 2011 Arab Spring uprising.

An estimated 46,000 nongovernmental groups, including nonpolitical organizations, are operating in the country. The measure gives them a year to comply or face court action.

Many of the groups are charities that provide food, clothing, health care, and education to the poor. Under the new law, donations to nongovernmental groups must be preapproved by the government if they exceed $550.

The law also bans groups from engaging in political activities that officials determine are a threat to national security, order, health, and public morals.

In a separate development Monday, foreign and defense ministers from Egypt and Russia met in Cairo to discuss a range of issues, including terrorism, Libya, and the resumption of flights suspended since 2015 terrorist attack.

Along with Sissi, Defense Minister Sedki Sobhi, and Foreign Minister Sameh Shurki met with their Russian counterparts, Sergey Shoygu and Sergey Lavrov.

Shurki said that Russia and Egypt will continue to speak against countries harboring terrorists and providing militants a ‘‘safe haven.’’ He said that militant groups are using Libya as a ‘‘staging ground to threaten Egyptian national security.’’

Also Monday, Egypt announced a $2.49 billion package of income tax discounts, bonuses for state employees, increased pension payments, and cash subsidies for lower and middle income Egyptians to cope with soaring inflation.
