Washington: President Donald Trump said Saturday he's still considering military action against Iran after it downed an unmanned US military aircraft, saying the use of force is "always on the table until we get this solved."
The president said he aborted a military strike set for Thursday after learning 150 people would be killed.
"I don't want to kill 150 Iranians. I don't want to kill 150 of anything or anybody unless it's absolutely necessary," he told reporters as he left the White House for a weekend at the Camp David presidential retreat.
Trump said "we very much appreciate" a decision by Iran's Revolutionary Guard not to shoot down a US spy plane carrying more than 30 people. He said the downing of the US drone was "probably intentional" contradicting what he said Thursday.
The president's comments came as Iran summoned the United Arab Emirates' top envoy to Tehran to protest the neighboring Arab nation's decision to allow the US to use a base there to launch the drone that Iran says entered its airspace, state media reported Saturday.
Iran issued a "strong protest" to the UAE diplomat, saying Iran does not tolerate the facilitation of foreign forces that violate its territory, the report by the official IRNA news agency said.
The US said its RQ-4A Global Hawk was shot down Thursday over international waters in the Strait of Hormuz, not inside Iranian airspace.
The shoot-down by elite Iranian Revolutionary Guard forces marked the first time the Islamic Republic directly attacked the American military amid mounting tensions over Tehran's unraveling nuclear deal with world powers.
The two countries disputed the circumstances leading up to an Iranian surface-to-air missile bringing down the drone, an unmanned aircraft with a wingspan larger than a Boeing 737 jetliner and costing over USD 100 million.
British diplomat Andrew Murrison planned to visit Iran on Sunday and call for the "urgent de-escalation in the region and raise UK and international concerns about Iran's regional conduct" during talks with Tehran's government, Britain's Foreign Office said in a statement Saturday.
"At this time of increased regional tensions and at a crucial period for the future of the nuclear deal, this visit is an opportunity for further open, frank and constructive engagement with the government of Iran," the statement said.
The announcement came a day after Trump said he had called off military strikes on Iran minutes before they were to be carried out Thursday because it would have been out of proportion to the shootdown of an unmanned American surveillance drone.
The drone incident immediately heightened the crisis already gripping the wider region, which is rooted in Trump withdrawing the US a year ago from Iran's 2015 nuclear deal and imposing crippling new sanctions on Tehran.
Recently, Iran quadrupled its production of low-enriched uranium to be on pace to break one of the deal's terms by next week, while threatening to raise enrichment closer to weapons-grade levels on July 7 if Europe doesn't offer it a new deal.
In Iraq, security measures were increased at one of the country's largest air bases, which houses American trainers, a top Iraqi air force commander said Saturday.
The US military said operations at the base were going on as usual and there were currently no plans to evacuate personnel.
The stepped-up Iraqi security measures at Balad air base, just north of the capital of Baghdad come amid the sharply rising tensions in the Middle East between the US and Iran.
On Friday, Iran summoned Swiss Ambassador Markus Leitner to hear Iran's protest over the alleged violation. Switzerland looks after US interests in Iran. Tehran and Washing have had no diplomatic relations since 1979.
Iran said the US drone was a "very dangerous provocation.

New Delhi (PTI): India on Wednesday asked all its nationals residing in Iran to leave by available means and avoid any travel to the country as tensions mounted over possible military intervention by the US over Tehran's crackdown on nationwide protests that killed over 2,500 people.
In a fresh advisory, the Indian embassy in Tehran urged all Indians, including students, pilgrims, business persons and tourists, to leave Iran by available means of transport, including commercial flights.
According to estimates, a little over 10,000 Indians, including students, are currently living in Iran.
The mission also urged all Indian citizens and PIOs (Persons of Indian Origin) to exercise due caution, avoid areas of protests or demonstrations and stay in contact with the embassy.
It also urged the Indian nationals to have their travel and immigration documents, including passports, readily available. Indians living in Iran on resident visas were also advised to register with the embassy.
In case any Indian national is unable to register due to internet disruptions in Iran, their families in India are requested to do so, the mission said.
"In view of the evolving situation in Iran, Indian nationals who are currently in Iran (students, pilgrims, business persons and tourists) are advised to leave Iran by available means of transport, including commercial flights," the embassy said.
India's advisory came amid rising tensions in Iran and the region after Trump indicated military action if Tehran continues its crackdown on the protesters.
"If they hang them, you're going to see some things... We will take very strong action if they do such a thing," the US president told CBS News.
In a message to the protesters, Trump said on Tuesday that "help is on the way". The US president has already announced a 25 per cent tariff on countries having trade with Tehran.
The protests began late last month in Tehran after the Iranian currency rial plunged to record lows. The protests have since spread to all 31 provinces, evolving from an agitation against economic woes to a demand for political change.
Separately, the Ministry of External Affairs (MEA) advised Indians to avoid travelling to Iran.
In view of the ongoing developments in Iran, Indian nationals are once again strongly advised to avoid travel to the Islamic Republic of Iran until further notice, it said.
In a previous advisory issued on January 5, the MEA urged its nationals to avoid non-essential travel to Iran.
It had also asked Indian citizens and PIOs residing in Iran to exercise due caution and avoid visiting areas of protests.
The overall situation in Iran in the last few days has deteriorated dramatically as the death toll from the nationwide protests has increased to over 2,500, according to US-based Human Rights Activists News Agency (HRANA).
