"Qatar has been an impartial diplomatic mediator in resolving crises and disputes between brotherly and friendly countries and will continue to be a major player in the global community", the ministry said in a statement. The sale is hoped to give "increase security cooperation and interoperability" between the two countries.
Erdogan said it appears that some countries had chose to hand down the death penalty to Qatar and urged Saudi Arabia to reconsider the harsh steps.
In the last week, while the restrictions have been in place, Qatar Airways has operated 1,200 flights between Doha and more than 150 destinations "with 90% of those flights departing within 15 minutes of their scheduled departure time", Qatar Airways said. Turkey and Qatar have both provided support for the Muslim Brotherhood in Egypt and backed rebels fighting to overthrow Syrian President Bashar al-Assad.
Kalin said a Turkish military base in Qatar, set up before the regional spat, was established to ensure the security of the whole region and did not pose any military threat to any other country.
Egypt, Saudi Arabia, Bahrain and the UAE announced about breaking their diplomatic relations with Qatar June 5, accusing Doha of supporting terrorist organizations and destabilizing the situation in the Middle East. "I think that as the elder statesman of the Gulf, the king of Saudi Arabia should solve this affair and show leadership", said Erdogan.
But experts were taken aback by the announcement of the arms deal, which came just five days after he said Qatar has "historically been a funder of terrorism at a very high level".
Qatar is home to 11,000 USA troops and the Al Udeid Air Base, the main regional center for air operations against the terrorist group.
Qatar is also home to the forward headquarters of US Central Command, which leads US military action against IS in Iraq and Syria.
Qatar, for its part, strenuously denies accusations that it is a supporter of terrorism, describing moves to isolate it by its fellow Arab countries as "unjustified".
