Hello and welcome to the program.

This is News Hour from the BBC World Service, coming to you live from London.

I'm Paul Henley.

The head of the World Health Organisation has called on Israel to stop attacks on healthcare centres

after strikes on NASA Hospital in southern Gaza,

reportedly killed at least 20 people today,

including five journalists. Britain's foreign minister said he was horrified. The Israeli

militaries issued a statement saying it regrets any harm to what it called uninvolved individuals,

but that it does not target journalists. In video from the scene, a doctor standing at an entrance to what is the second largest,

the largest, rather, remaining functioning hospital in southern Gaza,

holds up bloodied clothes to show journalists following the first strike.

Suddenly, there is a second explosion, sending people running for cover as glass shatters.

Dr. Mohamed Saka is Director of Nursing at NASA Hospital.

He was that doctor speaking to journalists at the time of the second strike.

I was in front of the emergency department of NASA Medical Complex.

I was holding a uniform of a female nurse.

She was attacked by the first air strike. Her uniform was full of blood

and a lot of penetrating shrapnel. I was holding this uniform and talking to the journalists,

telling them that this nurse has been attacked and seriously injured while she was working in the O.T.

of NOS Medical Complex. While I was talking to them, the second airstrike hit strongly, resulted in many casualties and mortalities among our staff and other journalists,

in addition to patients inside the complex.

Every day I'm losing my colleagues, one after one, die every day.
