Damascus has sent a letter to the United Nations accusing some Lebanese areas of helping al-Qaeda and the Muslim Brotherhood to take root along the Syrian border.
"Some Lebanese areas next to the Syrian border are incubating terrorist elements from al-Qaeda and the Muslim Brotherhood, who are messing with the security of Syrian citizens and work on undermining the United Nations Special Envoy's plan," Syrian UN Ambassador Bashar Ja'afari wrote.
The letter was sent to UN Secretary-General Ban Ki-moon and the Security Council.
"In some areas [of Lebanon] ... warehouses have been set up for weapons and ammunition that is arriving to Lebanon
illegally, either by sea, or sometimes through using the planes of specific countries to transport weapons to Lebanon and then smuggle them to Syria, under the excuse that they [aircraft] are carrying humanitarian aid for Syrian refugees," Ja'afari said.
He specifically said charities run by Lebanese Salafists and the Future Movement, led by the son of assassinated Prime Minister Rafik al-Hariri, were being used to provide safe haven to terrorists in Lebanon.
