Important cultural institutions in the capital include the Iraqi National Symphony Orchestra – rehearsals and performances were briefly interrupted during the Occupation of Iraq but have since returned to normal. The National Theatre of Iraq was looted during the 2003 invasion, but efforts are underway to restore it. The live theatre scene received a boost during the 1990s when UN sanctions limited the import of foreign films. As many as 30 cinemas were reported to have been converted to live stages, producing a wide range of comedies and dramatic productions.
