The Turkish NGO IHH Humanitarian Relief Foundation is continuing to provide support to Syrians, despite the barriers it faces Anadolu Agency reported.
The organization, which is active in more than 100 countries, sent 229 trucks of aid from Turkey to Syria on Sunday, said IHH's head Bulent Yildirim.
Altogether IHH helped about 500, 000 people in Syria, saidIHH press representative Mustafa Ozbek.
The aid convoy was formed as part of the "For the Vicinity Rights" and "I need you!" campaigns, launched to help Syrian refugees and civil war victims, to which thousands of Turkish people contributed to by collecting humanitarian aid to Syrians.
Yildirim said IHH face obstacles in crossing the Syria border to reach people in need, such as those in the Yarmouk Palestinian refugee camp near Damascus.
"The Islamic State of Iraq and the Levant and Kurdish Democratic Union Party (PYD) are trying to prevent aid from reaching Syria," Yildirim said.
"So far, 2,300 trucks of humanitarian aid have been sent to Syria," he said, adding the organization does not discriminate in delivering aid.
Meanwhile, cease-fire agreements were struck between Syria's army and armed groups last week for Babila, Moadamieh, Qudsaya, Beit Sahm, Yalda, Barzeh and Yarmouk refugee camp, to allow for the delivery of provisions to opposition-controlled districts.
The new band of vehicles comprises 229 trucks loaded with with food, baby food, medicine, health supplies, diapers, clothing, shoes, tents, mattresses and comforters, saidIHH in a press release.
"Another convoy of 154 trucks from 59 provinces of Turkey are departing simultaneously. Only yesterday 75 trucks departed from Istanbul, which makes up the biggest part of the 229 trucks prepared to help Syrian people," Yildirim said.
The aid is planned to be given to thousands of people who are stuck near the border line, and later they will travel to Aleppo and Damascus, and the besieged Yarmouk camp.
