The world this week-Politics
Tributes were paid to Antonin Scalia, one of the justices on America's Supreme Court, who unexpectedly died while holidaying in Texas.
The political bickering over replacing him was less dignified.
Barack Obama said he would nominate a successor to the conservative Mr Scalia.
That person would need to be confirmed by the Senate.
Republicans argued for a delay until the next president takes office in 11 months' time, undoubtedly in the hope that he will be one of their own.
A federal judge in California ordered Apple to help unlock the iPhone used by one of the Islamists who attacked an office party in San Bernardino last December, killing 14 people.
The FBI wants Apple to disable the password feature.
But the company is not complying, arguing that building the software to unlock the phone “would undeniably create a backdoor” to its encryption protocols and give the government “power to reach into anyone's device to capture their data”.
Trucks carrying aid entered several besieged towns in Syria, including the rebel-held town of Muadhamiya, near the Syrian capital, Damascus.
This came ahead of a planned “cessation of hostilities” in Syria's war, thrashed out by America and Russia in Munich.
No one expects the ceasefire to take hold.
Members of opposition parties in the Democratic Republic of Congo went on strike to protest against efforts by Joseph Kabila, the president, to run for a third term in office.
Britain was on the brink of agreeing on new terms for its membership of the EU at a summit on February 18th and 19th, clearing the way for a referendum in June.
David Cameron, the prime minister, was confident of securing a deal in Brussels, but Eurosceptics back home were poised to criticise whatever emerged from the talks.
The European summit would also tackle the refugee crisis.
Austria set a daily cap of 3,200 migrants whom it will allow to cross its borders.
It also tightened border controls with countries in the Balkans that migrants cross to reach Austria.
Many then travel on to Germany and Sweden.
Turkey's prime minister, Ahmet Davutoglu, cancelled a visit to Brussels after a bomb in Ankara, the Turkish capital, killed at least 28 people.
The device was detonated close to the defence ministry as an army bus was passing by.
Turkey blamed Kurdish rebels.
Russia filed a lawsuit in a court in London to try to get Ukraine to repay a $3 billion bond.
Ukraine says that Russia has refused to take part in negotiations over restructuring the debt.
Meanwhile Ukraine's prime minister, Arseniy Yatsenyuk, survived a vote of no confidence in parliament after the country's president, Petro Poroshenko, called on him to step down, ostensibly over the slow pace of reforms.
The economy minister recently resigned and blamed Mr Poroshenko for hindering reform.
