Layla Moran told the British government to match its tough tone on Israel with the action as she warned people in Gaza to face “unbearable levels of cruel poverty.”

Lib Dem MP calls for further action, including recognition of the Palestinian state, to re-called Mohammad's family, whose NHS doctors ran her business last year and whose elderly parents are still trapped in northern Gaza.

He described the conditions on the ground as "slaughterhouses" and said people were on the verge of hunger.

The Guardian spoke with the two last October when Mohammad's parents were trapped at home. Soon after, they were forced to flee It killed his cousin and nephew in a strike.

Since then, they have returned and become one of the lucky few nearby people to "hold the walls on one side".

In recent weeks, the government has adopted a more important tone towards Israel. On Wednesday, Central and Eastern Central Minister Hamish Falconer called Israel’s aid blockade “shocking”, “brutal” and “irrefutable”, while Foreign Secretary David Lammy said Britain spoke with France and Saudi Arabia at a meeting in June.

"I'm frustrated that although the government's words and tone have changed in terms of specific actions, it hasn't changed much," Moran said.

She called on the government to recognize the Palestinian state, which will "protect the interests of Palestine and send a very clear signal to Israel that its actions have consequences". She also condemned the government for allowing trade in illegal settlements and “still arming Israel when it shouldn’t be done.”

Moran said the plight of the Mohammed family “reminds us that we have British citizens affected by what is happening in northern Gaza”.

Mohamed, who had worked in the Ministry of Health Services for 20 years, grew up in the Jabbaria refugee camp. He regularly contacts his family who are stuck in Gaza.

"The entire population has been squeezed into about a few kilometers," he said. "A very small area without shelter, without food, nothing. It's undescribable."

"People really starved because there's nothing left. Over the past three months, they haven't seen the proper food or help."

His brother-in-law called him from northern Gaza on Saturday morning, and the Israeli rockets came down from the sky. Overnight, Israeli air strikes killed at least 100 people. As the lockdown imposed by Israel appears to be entering Week 11, hunger and hunger prevails.

"Everything was destroyed there. In the waves of first hunger, people used to use dice. Now, there is no such.

"The bomb will not be able to kill everyone, it is hunger," he said.

Mohammed said when he called his parents, they told him, “We are fine, we are managing.” He was particularly worried about their health. His mother suffered from diabetes and high blood pressure, and his father removed the colon and made him vulnerable.

"(My brother-in-law) said, "Your father won't tell you because he doesn't want you to worry too much about you." "Anyone who is a little vulnerable is basically dead."

Mohammad was told of despair conditions on the ground, describing “people who died of hunger and bombing” and those who were infected or hit by missiles that could not be found for treatment.

He said: “Anyone who was injured is unfortunate because they died.

His brother-in-law told him: "People without skin. The missiles they fired burn the skin. They told you, 'I wish I could die.'" He also described the soaring prices of basic foods and basic foods including tents and sugars, adding that "oil is sold in 5ml, 10ml or 20ml or 20ml units" to measure it.

Moran, who has established a friendship with Mohammad when he recovered from surgery, said: “Hunger should not be a weapon of war, the unbearable cruelty is Mohammad’s family describing the story of Mohammad, but their stories are only millions now, and now in Northern Gaza, what seems to be worse than at the beginning is being trapped in Northern Gaza.

“It must stop immediately and the UK government needs to redouble its efforts to achieve this.”
