European nations are examining extending the lockdowns put in place to try to stem the coronavirus outbreak. A lockdown imposed on 12 March in Italy, where the number of deaths may soon overtake China, will now extend beyond the original 25 March end date. France said its 15-day lockdown might also be extended, with European leaders reluctant to give any deadline for an end to crisis measures. There have been 207,000 cases worldwide with more than 8,600 deaths. The European Central Bank (ECB) has launched an emergency €750bn ($820bn; £700bn) package to ease the impact of the pandemic, with boss Christine Lagarde tweeting "there are no limits" to its commitment to the euro. Europe's markets stabilised on opening, moving into positive territory, although Asian markets remained volatile with the Nikkei closing down 1%. The EU has introduced strict border controls. Travellers from outside are being turned away from airports and borders after the 27-country bloc imposed a 30-day ban to halt the spread of coronavirus. But EU leaders also agreed that internal borders that have been erected in recent days should come down. Separately, the EU's Brexit negotiator, Michel Barnier, said he had tested positive for coronavirus. He said on Twitter: "I am doing well and in good spirits." It is unclear how the pandemic will affect Brexit talks. The latest round was delayed on Wednesday but the UK government said it would look at different ways to continue discussions.
