Two US warships have arrived in the Persian Gulf for a joint exercise with the Qatari Navy. According to Qatar’s Ministry of Defense, the American warships arrived at Hamad Port south of Doha on Wednesday. The joint exercise comes at a time when Qatar is embroiled in a crisis with its fellow Arab rivals in the Persian Gulf. U-S Secretary of Defense Jim Mattis and his Qatari counterpart Khalid al-Attiyah also signed a 12-billion dollar deal under which Washington will sell F-15 fighters to the country. Meanwhile, Turkey’s Foreign Minister, Mevlut Chavushoglu who arrived in Qatar on Wednesday, urged dialogue to end the crisis. Chavushoglu made the demand after meeting with Qatari Emir Sheikh Tamim bin Hamad Al Thani as well as Foreign Minister Sheikh Mohammed bin Abdulrahman. He is slated to travel to Kuwait on Thursday, before holding talks with Saudi King Salman in Saudi Arabia on Friday.
