Israel has warned the Houthis in Yemen that its action against them has only just begun.

The warning came after a series of Israeli strikes on Yemen killed at least six people.

The head of the World Health Organization has said he was metres away from the strike on a major airport.

Tedros Adhadam Gubriyasas said he was about to board a flight in the capital Sanna when the bombardment began.

His spokesperson, Stephanie Tremblay, read out a statement on his behalf and said,

Gabriessus is now concerned about what could unfold.

The Secretary General remains deeply concerned about the risk of further escalation in the region

and reiterates his call for all parties concerned to cease all military actions and to exercise utmost restraint. He also warns

Well, this is the second Israeli air strike in the span of a week.

And the main focus of the Israeli military is essentially Houthi military infrastructure, energy infrastructure, and main ports.

And if you look at what they've hit, for example, in this air strike, first of all, the focus is the capital Sana'a, so the airport, the international airport was hit, but also the port city of Hadaida.

Both those locations have been hit multiple times, more than once, also in last week's

air strike.

But they've hit two main ports, they've hit power stations and the airport.

And the Israeli government says there are two main aims, if you will, or they've named two aims.

One is that they said they've hit military targets used to transport Iranian arms into the region.
