"Turkey doesn't have a minute to lose, above all at a time of war between Iran and Israel," said DEM co-president Tulay Hatimogullari, who said practical steps to bring about the dissolution of the PKK were moving too "slowly".

Her remarks came on the sixth day of an expanding air war between Israel and Iran that has raised fears that efforts to repair broken ties between the Turkish state and the country's Kurdish minority could grind to a halt.

"It's time the government did what it needs to do," said her co-chair Tuncer Bakirhan, echoing calls for an easing of the conditions for jailed PKK founder Abdullah Ocalan who led the call for his militants to disarm.

The pair also pushed for the creation of a bipartisan parliamentary committee to oversee the ongoing process, which is currently being negotiated by DEM, the government and the PKK.

They said the disarmament process would gather momentum if the government pushed ahead with measures to advance "democratisation" such as taking steps to normalise the use of the Kurdish language.

The PKK announced its dissolution on May 12, ending more than four decades of guerrilla warfare that claimed over 40,000 lives, responding to a call in February by Ocalan, who has been jailed on a prison island off Istanbul since 1999.
