San Francisco, July 10 : Facebook discontinued last year a small helicopter drone project that could temporarily replace cellular services in emergency situations, The Verge reported.

The project was discontinued a few months after being shown off at the F8 developer conference in May of 2017, said the report on Monday.

"Tether-tenna was a proof of concept project we were evaluating when we discussed it at F8 in early 2017," a spokesperson for Facebook was quoted as saying.

The idea was to send a helicopter equipped with telecommunications equipment hundreds of metres up in the air to be able to tether to fiber and power lines in places where wireless capacity was compromised due to disaster or other factors.

"It wasn't something we pursued further as we chose to focus our efforts on continued development and advancement of our Terragraph, millimeter-wave, and HAPS (high altitude platform station) programmes," the Facebook spokesperson added.

The Tether-tenna is, however, not the only aerial Internet project that Facebook has abandoned in recent times.

In June this year, Facebook announced it decided to abandon its plan to develop high-flying solar-powered drones called Aquila that was aimed to deliver Internet to nearly four billion people in remote parts of the world.

A high altitude platform station (HAPS) system, Aquila's mission, according to Facebook CEO Mark Zuckerberg, was to connect the world and help people who do not have online access all the opportunities of the Internet.

Facebook began Aquila project in 2014. In 2017, the solar-powered drone successfully completed the second full-scale test flight.

Tether-tenna was a much smaller scale idea compared to Aquila.

Tel Aviv, Dec 21: A rocket fired from Yemen hit an area of Tel Aviv overnight, leaving 16 people slightly injured by shattered glass, the Israeli military said Saturday, days after Israeli airstrikes hit Houthi rebels who have been launching missiles in solidarity with Palestinians.

A further 14 people sustained minor injuries as they rushed to shelters when air raid sirens sounded before the projectile hit just before 4 am Saturday, the military said.

The Houthi rebels issued a statement on the Telegram messaging app saying they had aimed a hypersonic ballistic missile at a military target, which they did not identify.

The attack comes less than two days after a series of Israeli airstrikes on Yemen's Houthi rebel-held capital, Sanaa, and port city of Hodeida killed at least nine people. The Israeli strikes were in response to a Houthi attack in which a long-range missile hit an Israeli school building. The Houthis also claimed a drone strike targeting an unspecified military target in central Israel on Thursday.

The Israeli military says the Iran-backed Houthis have launched more than 200 missiles and drones during the Israel-Hamas war in Gaza. The Houthis have also been attacking shipping in the Red Sea and Gulf of Aden and say they won't stop until there is a ceasefire in Gaza.

The Israeli strikes Thursday caused “considerable damage” to the Houthi-controlled Red Sea ports “that will lead to the immediate and significant reduction in port capacity,” UN spokesman Stephane Dujarric said. The port at Hodeida has been key for food shipments into Yemen in its decade-long civil war.

UN Secretary-General Antonio Guterres said both sides' attacks risk further escalation in the region and undermine UN mediation efforts.
