GAZA/JERUSALEM/RAMALLAH/MADRID - Hamas on Tuesday accused Israeli authorities of "disregarding" demands from mediators and international organizations to allow humanitarian aid into the Gaza Strip.

"The Israeli occupation allowed only 200 trucks to enter Gaza on Monday, in continued breach of the ceasefire agreement, which stipulated the entry of 600 trucks daily," Hamas spokesperson Hazem Qassem said in a press statement.

Meanwhile, Bassam Zaqout, Gaza's medical relief director, warned that the shortage of medical supplies and Israeli restrictions on crossings are threatening the lives of thousands of wounded and sick people, especially cancer patients.

Between 5,000 and 10,000 cancer patients in the Gaza Strip are suffering from a lack of specialized medications and diagnostic equipment, according to Zaqout.

The United Nations Relief and Works Agency for Palestine Refugees in the Near East (UNRWA) also said that People in Gaza are increasingly suffering from skin infections due to the surge in pests, including rats, lice, fleas, and mites.

Separately, two Palestinians, including a child, were killed and several others injured on Tuesday in Israeli airstrikes on Gaza City, according to Palestinian sources.

Mahmoud Basal, spokesperson for the Civil Defense, told Xinhua that an Israeli airstrike targeted a police station in the Sheikh Radwan area in northwest Gaza City, killing a child and wounding five others, some critically.

In another incident, a Palestinian was killed in an Israeli airstrike targeting a group of civilians in southern Gaza City, Basal said.

Flotilla activists' detention extended

Also on Tuesday, an Israeli court extended by six days the detention of two activists detained aboard a Gaza-bound flotilla in international waters by the Israeli navy last week.

The activists, Thiago Avila of Brazil and Saif Abu Keshek of Spain, were brought to Israel after Israeli forces seized the vessels. Others aboard the flotilla were reportedly taken to the Greek island of Crete and released.

During the hearing at the Ashkelon Magistrate's Court, police told the court the two were suspected of aiding an enemy, contact with a foreign agent, and ties to a terrorist organization. Court documents show police identified the pair as "dominant figures" in the flotilla and claimed to possess material supporting the allegations.

Adalah, an Israel-based rights group representing the men, said both have launched a hunger strike and deny all charges. Adalah lawyers described the accusations as "baseless" and alleged the men are being held in harsh conditions and subjected to abuse.

The lawyers further argued that Israel lacks jurisdiction, noting the activists were detained more than 1,000 kilometers from Gaza and are not Israeli citizens.

'No justification for arrest'

Speaking on Spanish public broadcaster RTVE, Spanish Foreign Minister Jose Manuel Albares said there was "no evidence" to justify what he called the "illegal" arrest of activists from the Global Sumud Flotilla.

Albares said Palestinian-Spanish Saif Abu Keshek and Brazilian national Thiago Avila were detained after their flotilla, which had departed from Spain, was intercepted by Israeli forces in international waters near Crete, around 600 km from the Israeli coast.

He said Israel had not presented evidence linking Keshek or Avila with the alleged charges of "collaborating with the enemy in times of war, contacting a foreign agent, belonging to a terrorist organization and providing it with services, and transferring assets to a terrorist organization".

Albares said he would avoid comments that could affect Keshek's situation, adding that neither country would "abandon" its citizens.

'Orange line' aims to seize Gaza land

Meanwhile, Palestinian National Council Chairman Rawhi Fattouh said the Israeli army's creation of the so-called "orange line" in the Gaza Strip aims to seize more land and shrink the territory.

In a press statement, Fattouh said, "The so-called orange line ... is an extension of colonial policies aimed at seizing more land, shrinking the enclave, and imposing a forced reality" on the Palestinian people.

Fattouh emphasized his condemnation and rejection of any control over the Gaza Strip's land, considering these "measures, along with what is known as the yellow line, to be a colonial and ethnic cleansing approach aimed at displacing the population".

He added that Israel controls over 59 percent of the enclave's area, which constitutes "a blatant violation of international law and signed agreements".

The Israeli army has not issued any official comment on the creation of the "orange line." However, Israel's state-owned Kan TV News reported Monday that the Israeli army has pushed the so-called "yellow line" westward in the Gaza Strip, thereby forming what is referred to as the "orange line."
