During Ramadan, Muslims around the world abstain from eating, drinking, smoking and having sex from dawn to dusk

A court in northern Tunisia handed one-month jail terms Thursday to four men for eating in public during the Muslim dawn-to-dusk fasting month of Ramadan, a spokesman said.

The four had been "eating and smoking in a public garden, a provocative act during Ramadan", which started last week, Chokri Lahmar, prosecution spokesman at the court in Bizerte, told AFP.

He said the four men had 10 days to appeal against their one-month sentences before the terms take effect.

Their sentencing, which followed complaints from other local residents, comes ahead of a call circulated on social media for a June 11 demonstration to protect the rights of those who decline to take part in the Ramadan fast.

Although the state has the role of "guardian of religion" under the constitution, Tunisia has no specific law banning eating in public during Ramadan, a controversy which resurfaces each year in the North African country.

Most restaurants and coffeeshops remain shut in Tunisia during daylight hours over the holy month, but some establishments open behind closed curtains to prevent customers from being seen.

During Ramadan, Muslims around the world abstain from eating, drinking, smoking and having sex from dawn to dusk.

They break the fast with a meal known as iftar and before dawn they have a second opportunity to eat and drink during suhur.
