US authorities denied entry to Pakistan’s ambassador to Turkmenistan and deported him from Los Angeles. Ambassador K K Wagan, who holds a valid US visa and all necessary travel documents, was stopped at Los Angeles airport by US immigration authorities, The News quoted diplomatic sources as saying. Foreign Office confirmed the envoy had gone to the US on a private visit. It said the Ministry of Foreign Affairs was looking into the matter and an investigation was underway. The officials forced him to return to his last port of departure, raising concerns about diplomatic protocol and the nature of the decision. It remains unclear what specific concerns triggered this response from American authorities. Wagan is likely to be called back to Islamabad to explain his position, sources said. The Foreign Ministry has, meanwhile, directed its Consulate in Los Angeles to investigate the case, sources say. The incident has already been communicated to Pakistan’s Foreign Minister Ishaq Dar and Foreign Secretary Aamna Baloch who were reportedly briefed on the matter. The US immigration system flagged Wagan over “controversial visa references”, leading to his immediate deportation.
