A two-day lockdown came into effect in the Gaza Strip on Friday to curb a worsening COVID-19 outbreak.
Until Sunday at 7 am (0500 GMT), all shops except pharmacies are to be closed and people will be barred from leaving their homes except for health reasons.
A nighttime curfew has been in place since August.
Police and security forces were deployed in the streets of the Palestinian enclave on Friday to implement the curfew in all districts, which were separated from each other and divided into blocks to facilitate control.
The Hamas-run interior ministry said the measures aim to reduce contact and overcrowding in light of the rise of coronavirus cases in the territory.
General Ali Al-Nadi, director of police operations and communications, said that violations of the measures would not be tolerated. In case of an emergency, citizens could call toll-free numbers at the police or the ministry.
The number of infections has recently spiked in Gaza, where 2 million people live in cramped conditions with poor infrastructure.
The health ministry reported 617 new cases in the last 24 hours in Gaza, for a total of 17,425 cases. There have been some 175 virus-linked fatalities.
The United Nations Relief and Works Agency for Palestine (UNRWA) has warned the enclave's health system could collapse if cases continue to increase.
