Iranians hit the streets to celebrate deal

After sundown on the 27th night of Ramadan, Iranians took to the streets to celebrate a deal that many hope will herald an easing of financial pressure and a new phase in the country's outlook.

Iranian journalist Aliasghar Shafieian wrote on Twitter that upwards of 600 people joined an impromptu and rapidly growing celebration in central Tehran's Valiasr Square.

Among the chants, according to Shafieian, were "Long live Rouhani," "Long live Zarif" and "Long live the reforms of Khatami," in reference to Mohammad Khatami, who served as president for eight years from 1997 and attempted to implement an ambitious raft of reforms including extending freedom of the press and reopening the embassies of all European countries.

A civil engineer in Iran, attending another nuclear deal celebration in Tehran's Vanak Square, said on Twitter that police had moved in when people began chanting "Political prisoners must be freed".
