BUDAPEST, Hungary – The Latest on Europe's migration crisis (all times local):

3:30 p.m.

Police in Germany say a Syrian asylum-seeker has died after trying to kill his estranged wife by setting her on fire in the town of Ruedesheim, west of Frankfurt.

A spokesman for Hesse state police says the 45-year-old man entered the building where his wife and three children were living early Thursday and poured a flammable liquid over her.

Markus Hoffmann said the 31-year-old woman suffered life-threatening injuries. One of their children is being treated for shock.

Hoffmann said the family had arrived in Germany together but the man, who was known to police over previous unspecified incidents, had later been housed separately.

He said the building, which housed 14 migrants, is now uninhabitable.

Three small opposition parties are calling for a boycott of a government-sponsored referendum seeking support for opposing any future European Union plans to resettle refugees among member countries.

Officials from the Modern Hungary Movement, Dialogue for Hungary and Together said Thursday that a billboard campaign supporting the boycott will be launched Sept 15. The parties hope to keep turnout below the 50 percent threshold needed for the vote to be valid.

The government says the referendum to be held Oct. 2 is an opportunity to reject EU migration policies and defend national sovereignty. Prime Minister Viktor Orban has described migrants as "poison" and Hungary built fences on its southern borders last year to stop the migrant flow.

Polls show a majority of Hungarians reject taking in migrants and refugees.
