Dubaiinfo-icon- The USinfo-icon military on Saturday searched for a missing pilot shot down over a remote area in Iraninfo-icon, while President Donald Trumpinfo-icon remained silent on the incident but reminded Tehraninfo-icon of his Monday deadline to open the Strait of Hormuzinfo-icon: "48 hours before all Hell will reign down on them."

The US warplane, identified by Iran as an F-15E Strike Eagle, was one of two attacked on Friday, with one service member rescued. Iran has promised a reward for whoever turns in the missing pilot. It's the first time the United Statesinfo-icon lost aircraft in Iranian territory during the warinfo-icon, now in its sixth week, which could further pressure Trumpinfo-icon to end the fighting.

Iran's joint military command on Saturday further said Iranian forces also struck two US Black Hawk helicopters the day before.

The war began with joint US-Israelinfo-icon strikes on Feb 28 and has killed thousands, shaken global markets, cut off key shipping routes and spiked fuel prices. It shows no signs of slowing as Iran responds with retaliatory strikes on US-Israeli bases across the region.

Trump earlier in the week said in a national address that the US has "beaten and completely decimated Iran". The US and Israel boasted that Iran's air defences were obliterated.

Iran hunts for enemy pilot'

A US crew member was rescued. But the Pentagon notified the US House Armed Services Committee that the status of a second service member wasn't known.

In a telephone interviewinfo-icon with NBC News, Trump said that what happened wouldn't affect negotiations with Iran.

Oracle's offices hit in Dubai

The Dubai headquarters of Oracle was hit after Iran's Revolutionary Guard accused the firm of assisting the US military. Footage verified by the AP outside the UAEinfo-icon showed a large hole in the building's southwestern corner.

Iran's veiled threat to disrupt second waterway

Iran's parliamentary speaker, Mohammad Bagher Qalibaf, issued a veiled threat late Friday to disrupt traffic through a second strategic waterway in the region, the Bab-el-Mandeb.

The strait, 32 kilometres (20 miles) wide, links the Red Sea with the Gulf of Aden and the Indian Ocean. More than a tenth of seaborne global oilinfo-icon and a quarter of container ships pass through it.

"What share of global oil, LNG, wheat, rice, and fertiliser shipments transits the Bab-el-Mandeb Strait?" Qalibaf wrote, referring to liquefied natural gas. "Which countries and companies account for the highest transit volumes through the strait?"

Nearly 2000 people, mostly civilians, have been killed in Iran since the war began.

In Lebanon, more than 1,400 people have been killed, and there have been more than 1 million displaced people. Ten Israeli soldiers have died there
