The USS Abraham Lincoln aircraft carrier, is seen at Naval Air Station North Island in San Diego last August. President Donald Trump reiterated that the U.S. and Iran are maintaining diplomatic talks, even after an earlier skirmish in the Arabian Sea spooked oil markets amid heightened tensions between the two countries. We are negotiating with them right now" and they'd like to do something," Trump told reporters at the White House on Tuesday. They had a chance to do something a while ago and it didn't work out, and we did Midnight Hammer," he said, referring to the June U.S. military strike in Iran. Earlier Tuesday, a U.S. F-35C warplane shot down a drone in self-defense as the unmanned aircraft aggressively approached" the USS Abraham Lincoln aircraft carrier with unclear intent," U.S. Central Command said in a statement. The command said no American service members were harmed and no U.S. equipment was damaged.

Iran says'ready for war' Which are Iran's main opposition groups? The United States military says it shot down an Iranian drone that approached a US aircraft carrier in the Arabian Sea, amid continued efforts by regional powers to ease tensions between Washington and Tehran. In a statement on Tuesday, US Central Command (CENTCOM) spokesperson Tim Hawkins said a US fighter jet from the USS Abraham Lincoln "shot down the Iranian drone in self-defense and to protect the aircraft carrier and personnel on board". CENTCOM said the drone "aggressively approached" the aircraft carrier with "unclear intent" and it "continued to fly toward the ship despite de-escalatory measures taken by US forces operating in international waters". There was no immediate comment from the Iranian authorities on the incident.

DUBAI, United Arab Emirates (AP) – The United States has joined the United Kingdom and Israel in accusing Iran of carrying out a deadly drone strike that killed two aboard a tanker off Oman. U.S. Secretary of State Antony Blinken made the announcement in a statement Sunday. Blinken said: "Upon review of the available information, we are confident that Iran conducted this attack, which killed two innocent people, using one-way explosive (drones), a lethal capability it is increasingly employing throughout the region." He added that there was "no justification for this attack, which follows a pattern of attacks and other belligerent behavior."

DUBAI, UNITED ARAB EMIRATES – A small instrument inside the drones that targeted the heart of Saudi Arabia's oil industry and those in the arsenal of Yemen's Houthi rebels match components recovered in downed Iranian drones in Afghanistan and Iraq, two reports say. These gyroscopes have only been found inside drones manufactured by Iran, Conflict Armament Research said in a report released on Wednesday. That follows a recently released report from the United Nations saying its experts saw a similar gyroscope from an Iranian drone obtained by the U.S. military in Afghanistan, as well as in weapons shipments seized in the Arabian Sea bound for Yemen. The discovery further ties Iran to an attack that briefly halved Saudi Arabia's oil output and saw energy prices spike by a level unseen since the 1991 Gulf War. It also ties Iran to the arming of the rebel Houthis in Yemen's long civil war.

WASHINGTON - A U.S. warship on Thursday destroyed an Iranian drone in the Strait of Hormuz after it threatened the ship, President Donald Trump said. The incident marked a new escalation of tensions between the countries less than one month after Iran downed an American drone in the same waterway and Trump came close to retaliating with a military strike. In remarks at the White House, Trump blamed Iran for a "provocative and hostile" action and said the U.S. responded in self-defense. He said the Navy's USS Boxer, an amphibious assault ship, took defensive action after the Iranian aircraft closed to within 1,000 yards of the ship and ignored multiple calls to stand down. "The United States reserves the right to defend our personnel, facilities and interests and calls upon all nations to condemn Iran's attempts to disrupt freedom of navigation and global commerce," Trump said.

A new study exploring depths of the Gulf of Oman revealed a massive increase in the size of its "dead zone," an area with too little oxygen for the survival of marine life. First spotted nearly half a century ago, dead-zones, aka oxygen minimum zones or OMZs, were flagged as a major threat to marine biology. They occur naturally at depths ranging from 700 to 2500 feet due to changes in the level of atmospheric oxygen and have been located in three to four parts of the world including the Gulf of Oman which shares its waters with the Arabian Sea. Now, that dead-zone appears to have grown bigger than what was previously thought. During a recent study, scientists from the University of East Anglia (UEA) sent two underwater robots, dubbed Seagliders, into the gulf to create a detailed picture of oxygen levels and the mechanics that mix oxygen and other nutrients into the water.
