Aid supplies are beginning to reach the besieged community of Eastern Ghouta for the first time in weeks — but the Syrian regime refused to allow many medical supplies, stripping them out of the aid convoy.The blocked supplies are "desperately needed to save lives and reduce suffering," the World Health Organization told NPR via email.Eastern Ghouta, a rebel-held suburb of Damascus, has been bombarded for months, with air strikes by the Syrian government and Russia accelerating sharply February. Some 600 civilians are estimated to have died in in the past few weeks.The U.N. Security Council demanded a cease-fire across Syria more than a week ago, but the bloodshed in eastern Ghouta continued. Then Russia called for a "humanitarian corridor" to be established, to allow civilians to leave and aid to enter.But convoys still weren't able to make it through — U.N. officials "said that lack of approvals and consensus among the warring parties, as well as the limited duration of the daily, five-hour pause, had made aid delivery impossible," the Associated Press reports.An estimated 400,000 people remained trapped in a dire situation, without food or medical supplies, amid ongoing air strikes, ground attacks and alleged chemical weapon attacks.Now, 46 trucks of supplies have reached Eastern Ghouta, as part of an inter-agency convoy arranged by aid groups and the United Nations.Monday's shipment includes enough food for more than 27,000 people, according to the U.N. and the Red Cross/Red Crescent, with more deliveries planned for later this week. The U.N.'s last aid delivery to the region was weeks ago, and the Red Cross last reached the area in November.But not all the supplies in Monday's convoy made it through: Seventy percent of the medical supplies were blocked by the Syrian government, a U.N. representative told The Associated Press."Three of the 46 trucks being sent to Duma today are close to empty," Marwa Awad, a spokeswoman for the U.N.'s World Food Program in Damascus, told The Associated Press.An official with the World Health Organization told NPR via email that the supplies were removed by government officials during an "obligatory routine inspection" of the convoy."All trauma [kits], surgical, dialysis sessions and insulin" were rejected by Syrian national authorities, spokesman Tarik Jasarevic said. The supplies remain with the WHO, which will attempt to send them again in a future convoy."Virtually no medical care available"Eastern Ghouta has been suffering from a critical shortage of medical supplies even as casualties from air strikes are mounting.Two weeks ago, Zedoun Al Zoebi, the CEO of the Union of Medical Care and Relief Organizations, said in a statement that "medicine and medical supplies have not been allowed into the city for months now, and there is virtually no medical care available for these people as they suffer severe trauma wounds."The deadly conflict in eastern Ghouta has been compared to the bloody fight for Aleppo in 2016, which also left hundreds of thousands of people trapped by bombardments, without access to food, fuel or medical supplies. That battle killed thousands of civilians, according to the White House.Syrian activist Kassem Eid, who used to live in Ghouta and now is in exile, joined NPR on Sunday to describe what his home was like before the war began:
