4-way emergency Ukraine summit planned for Wednesday

The leaders of Ukraine, Germany and France are pushing for a summit with Russian President Vladimir Putin on Wednesday in a frantic bid to halt escalating bloodshed in eastern Ukraine.
The four leaders discussed the meeting in a phone call Sunday as part of their efforts to achieve a "comprehensive settlement" in the conflict between Ukrainian forces and pro-Russian rebels, Berlin said.
Putin, however, warned that the summit planned in the Belarussian capital Minsk would only take place if the leaders agreed on a "number of points" by then.
"We will be aiming for Wednesday, if by that time we manage to agree on a number of points which we've been intensely discussing lately," Putin told Belarus President Alexander Lukashenko in televised remarks on Sunday.
German Chancellor Angela Merkel and French President Francois Hollande have ramped up their push for peace in recent days, jetting to Kiev first for talks with Ukrainian President Petro Poroshenko and then to Moscow to meet Putin, who the West accuses of masterminding the 10-month-old conflict.
On Monday, foreign ministry officials from the four countries will hold preparatory talks in Berlin while Merkel briefs US President Barack Obama on the latest peace initiative during a visit to the White House.   
In their telephone conversation on Sunday, Putin, Poroshenko, Merkel and Hollande "continued to work on a package of measures to achieve a comprehensive settlement of the conflict in eastern Ukraine," Merkel's office said.
The Ukrainian government said the leaders expected their efforts to lead to "an immediate and unconditional bilateral ceasefire".
Fresh fighting claimed 12 civilian lives, separatist and Kiev authorities said, with 12 Ukrainian troops also killed in the last 24 hours.
The conflict in the former Soviet republic has left at least 5,400 people dead.
A previous peace deal agreed in Minsk in September has been largely ignored, with fighting escalating in recent weeks as the rebels push further into government-held territory.
French Foreign Minister Laurent Fabius told a security conference in the German city of Munich that "what Germany and France are seeking right now is not peace on paper, but peace on the ground."
European Union foreign ministers meeting in Brussels on Monday are to confirm the addition of 19 people to a list of EU sanctions over the conflict in Ukraine.
- Divisions over arming Ukraine -
In Washington, Obama is set to host Merkel as the worsening violence confronts them with a choice between pursuing the risky peace talks or throwing more weapons into the war.
At home Obama is facing increasing calls to supply the outmatched Ukrainian army with more weapons to shore up its faltering defences.
But Merkel and many European nations believe weapons could not overturn the military mismatch between Ukraine and the might of the Russian army, and would simply escalate the conflict.
"I think that the progress Ukraine needs won't be achieved with even more weapons," Merkel told the Munich conference on Saturday.
"I am very, very doubtful."
Also speaking in Munich, US Secretary of State John Kerry dismissed talk of a rift with Europe on the issue.
"Let me assure everybody, there is no division, there is no split," Kerry said.
"We all agree that this challenge will not end through military means (but) the longer it takes, the more the off-ramps are avoided, the more we will be forced to raise the costs on Russia and its proxies."
- 'Listen to your people' -
A senior State Department official has said the new European peace plan is based on September's ceasefire deal.
Hollande told French TV station France 2 the proposal includes the creation of a 50- to 70-kilometre (31- to 43-mile) demilitarised zone around the current demarcation line.
But this idea appeared to face opposition from Ukraine's president, who has lost territory to the rebels since the Minsk accord.
"There is only one line, and that's the line from the Minsk agreement," Poroshenko said.
Putin, meanwhile, heads to Egypt for a two-day visit on Monday in what experts say is in part a bid to show he has not been internationally isolated by the Ukraine crisis.
He gave an interview to Egyptian state newspaper Al-Ahram ahead of the visit, calling on the Ukrainian government to "listen to their people".
"It is evident that the crisis will continue until the Ukrainians themselves agree with each other," he said, according to a transcript released by the presidency.
Kiev accuses the rebels of sending more tanks, armoured vehicles and rocket launcher systems to the embattled Debaltseve region and to Granitne, around 35 kilometres (20 miles) northeast of the city of Mariupol.
The town of Debaltseve -- mid-way between the rebel centres of Donetsk and Lugansk -- has been the focus of fierce fighting for over a week as insurgents try to encircle government troops holding the strategic railway hub.
