'There is a vital urgency on this issue because of Iran's own actions and the trajectory of its nuclear program,' says FM Le Drian

After months of pessimism, both sides are speaking of progress and showing signs of flexibility, but time is short

Foreign Ministry spokesman says Tehran wants 'a lasting and credible agreement, and no agreement without these two components is on our agenda'

FM says he and US secretary of state addressed 'importance of putting pressure on Iran'; State Department says they also spoke about 'Russian aggression against Ukraine'

As negotiations resume in Vienna, Iranian spokesman says 'there can be no demands' beyond the nuke deal signed in 2015

Paris says 'regrettable' blastoff is a violation of UN Security Council resolutions; Iran admits rocket failed to put payload into correct orbit

Comments by top negotiator come days after European powers warned Tehran is nearing a point where escalation of its nuclear program ‘will have completely hollowed out’ 2015 deal

But State Department spokesman says it is 'too soon' to tell whether the movement is substantive

Britain, France and Germany warn there are 'weeks' left to reach agreement before Tehran's 'escalation of its nuclear program will have completely hollowed out' the 2015 pact

Islamic Republic has 'blown through' limits imposed by 2015 deal, says Rob Malley; Israeli defense official says Tehran not afraid of repercussions since 'there is no deterrent'
