Taxi-hailing services Careem and Uber suspended operations Saturday in Abu Dhabi – without any explanation.

The rival companies, which both began operating in Abu Dhabi in 2013, have acknowledged the temporary shutdown in in-app messages to users but have not explained why they suspended service or said when they expect to resume operations.

“This is a temporary suspension and we will let you know of any further updates,” an Uber spokesman in Dubai told Reuters .

Both companies are still operating in the neighboring emirate of Dubai.

The National quoted Careem as saying that they were working with Abu Dhabi's taxi regulator on the issue.

"Due to some unforeseen circumstances, we expect potential service interruptions in Abu Dhabi over the next few days," the company said. "We work with licensed vehicles in Abu Dhabi and we are working closely with TransAD to ensure both a reliable service and adherence to fleet requirements."

StepFeed has reached out to both companies for comment.

A daily income of $2.80 didn't stop refugees in Italy from giving back.

The group of impoverished refugees and asylum seekers living in a shelter banded together to donate to the victims of a devastating earthquake that rocked Italy, claiming 247 lives so far. The refugees joined in on rescue efforts.

“They wanted to make a small and symbolic gesture of solidarity with the victims of the terrible earthquake," said the manager of the project hosting the refugees. "Pictures and video of the earthquake made them think of the wars and disasters they fled from," he told Reuters .

The Independent reports that the 75 asylum seekers raised $226. According to Buzzfeed, the sum is equivalent to “each of them giving up one day’s worth of the 17.50 euro allowance they receive each week.”

One of the refugees said helping out empowered him: "This work is much more beautiful than a paid job".

From the Syrian refugee who launched a soup kitchen in Germany, to those who donated to the wildfire victims in Canada, refugees have long contributed to the communities that welcomed them.

"We hope that the kind of initiatives help fight stereotypes and misconceptions about refugees and migrants," said the director of an Italian organization that helps refugees.
