FNA - Iranian Ambassador to London Hamid Baeidinejad underlined the need for ending disruption of postal services to Iran by Britain's Royal Mail, warning to file a complaint with the Universal Postal Union (UPU).

"There are ongoing efforts to resolve the disruption of postal services to Iran from the UK, apparently due to operational issues. We hope that the issues would be resolved very quickly. Access to postal services is a fundamental civil right and should be ensured by all means," Baeidinejad wrote on his twitter page on Tuesday.

He cautioned that if the ongoing efforts to resolve the problems related to the issue fail to yield results, "we will use all possibilities to cancel this illegal act".

"Legally, the embassy will study the possibility for lodging a complaint with the local courts and the UPU against the Royal Mail and will try to find a way to send the postal items of our countrymen to Iran if the time of restrictions procrastinates," Baeidinejad stressed.

Last week, Britain's Royal Mail confirmed suspending mail delivery services to recipient addresses in Iran, citing Washington�s sanctions against the country.

The mail service said that services had already been suspended for the last two weeks and that any remaining parcel in Britain would be returned to the original sender.

Following the announcement, Baeidinejad said that the matter had been followed up with related British authorities, adding that a letter of protest had been sent to the UK�s Foreign Office.

He said that British authorities had promised to resolve the issue as soon as possible, requesting that they be given �until Monday� to address the problem.

Baeidinejad also said that UK authorities �were shocked� by the Royal Mail announcement.

The Iranian ambassador further stated that his mission in London itself would envision a channel to deliver parcels to Iran free of charge given that the problem persisted beyond the Monday deadline.

The suspension of mail delivery to Iran was allegedly done on the pretext of US sanctions targeting Iran.

US President Donald Trump withdrew Washington from the landmark Joint Comprehensive Plan of Action (JCPOA) agreement last May and renewed sanctions lifted under the agreement.

Iran has not left the deal despite Washington's measures, stressing that the remaining signatories to the agreement (including Britain) have to work to offset the negative impacts of the US pullout for Iran if they want Tehran to remain committed.
