A long queue lies behind - and a long and uncertain wait to cross into the unknown

Tens of thousands of Ukrainians are pouring towards neighbouring countries to flee the Russian invasion.

In the three days since the invasion began, more than 115,000 have crossed into Poland alone – some travelling for more than two days, others joining queues 15km (10 miles) long at border points.

Those fleeing are mostly women and children, as all Ukrainian men aged 18 to 60 are being told to stay and fight – in some cases separated from their families. BBC correspondents met them at the borders.

Ana had to leave her husband behind in Ukraine

Seen from the Moldovan border, Ukraine is a nation of women. Mothers and grandmothers, wheeling suitcases to safety, leading their children into the unknown.

Ana arrived at the Palanca crossing point after more than 24 hours of waiting in a queue on the Ukrainian side of the border – her little yellow car stuffed with bags, her six-year-old granddaughter singing to herself in the backseat.

Ana and her stepdaughter had driven straight from the southern city of Odesa – some 50km away and now a key target for Russia in the war.

But Ana’s calm smiling manner crumbled as soon as she began to speak. Breaking down in tears, she described how she’d had to leave her husband behind to defend their country.

“I hope the West will help us get out of this terrible situation because right now we’re facing the Russian aggressor alone.”

Around her, local volunteers from Moldova’s towns and villages waited to offer lifts to Ukrainians arriving here on foot.

But, like Ana, many who turn up here have thought only of escaping Ukraine, and have little idea of what happens now – for their country or themselves.
