Thin on the left so far
Only 1 of the 13 outlets with a published leaning rating that ran this story are rated left.
This story is still being watched, so it is a count and not yet a finding. Coverage keeps arriving for hours after an event, and a side that has published nothing this morning may publish by tonight. If it is still true when we stop checking, we will say so plainly.
Two United States Air Force KC-135 tanker aircraft have departed Bulgaria's Bezmer Air Base. Bulgarian Defence Minister Dimitar Stoyanov confirmed their departure on Saturday, stating they left the country on Friday. The aircraft had been stationed in Bulgaria to support US operations in the Middle East. Their deployment, authorised by Bulgaria's parliament from July 24 through October 1, had angered Iran.
Disagreement on flight purposes
Anadolu Ajansı reported that Minister Stoyanov stated all flights conducted during the aircraft's deployment were for training purposes over allied airspace. He distinguished these flights from a previous exercise that supported combat operations. However, the digests from Reuters, The Objective, Jerusalem Post, KAYHAN LIFE, The Straits Times, Market Screener, WTVB, The Mighty 790 KFGO, WKZO, WTAQ, KELO Newstalk 1320 107.9, and WSAU do not include details about the purpose of the flights or any distinction made by the minister.
What the coverage left out
None of the centre-rated or right-rated reports mention the minister's statement that all flights conducted during the aircraft's deployment were for training purposes over allied airspace. The centre-rated reports also do not include the detail that Bulgaria's parliament authorised the deployment of up to eight KC-135 military tanker aircraft, along with their crews and equipment, from July 24 through October 1.
