The Panama Papers data leak claims its first high-profile victim.

Iceland's Prime Minister Sigmundur David Gunnlaugsson stepped aside on Tuesday after being named in the Panama Papers leak that revealed his connection to an offshore company.

The embattled politician is the first major figure to be brought down by the leak from a Panamanian law firm of more than 11 million financial documents showing the tax-avoidance arrangements of the rich and famous around the world.

Many others are implicated in the Panama Papers leak.

British Prime Minister David Cameron admitted Thursday to having once held a stake in his late father Ian's offshore trust. Ian Cameron was among tens of thousands of people named in the law firm Mossack Fonseca's leaked documents, as were several friends of Russian President Vladimir Putin and Ukrainian President Petro Poroshenko, seen here giving two thumbs up behind U.S. President Barack Obama at the Nuclear Security Summit in Washington last Friday.

Here are some other big names implicated, including soccer star Lionel Messi.

The first wave of migrant deportees was sent from Greece back to Turkey.

Migrants camped out on the Greek island of Chios watched the arrival of a Turkish catamaran before it was loaded with some of their fellow migrants on Monday. The ferry held one of the first groups of deportees sent back to Turkey under a new European Union deal to address the mass migration and refugee crisis.

Over 51,000 people are stuck on Greece's Balkan border. 

While most of the deportees shipped off of Lesbos and Chios this week were economic migrants from Pakistan and Bangladesh, many Syrians seeking asylum in northern Europe, like these men and children lined up for food on Tuesday, remain trapped at the Greek-Macedonian border camp of Idomeni.

Under the EU deal, migrants arriving after March 20 are to be held in centres set up on five Aegean islands before being sent back to Turkey if their asylum applications are not accepted.

In France, it's now illegal to pay for sex.

Sex workers protested in Paris on Wednesday as French lawmakers debated a bill that would make it illegal to pay for sex. The bill passed, and under the new law, clients face fines between $2,200 and $5,000.

France follows Northern Ireland, Canada, Sweden, Norway and Iceland in introducing laws designed to punish the client without criminalizing those engaged in prostitution. The law, aimed at stamping out sex trafficking, paves the way for those who want to leave prostitution to receive residence permits and financial support.
