BETHLEHEM (Ma'an) -- Palestinian refugees in Bethlehem opened an exhibition of mosaic art on Sunday, following workshops teaching the ancient craft.

Palestinian painter Mujahed Khallaf is conducting mosaic workshops in refugee camps across the West Bank hoping to revive the art in Palestine.

Mosaic work has fallen out of practice after historically playing an important part in Palestinian cultural and artistic heritage, in particular mosaics in churches and other places of worship, a press statement said.

"The language of art is understood by everyone universally," it added.

The exhibition opened at the Phoenix Center in Dheisheh camp, displaying the work of 20 refugees who took part in the course with the support of German non-governmental organizations.
