Shipments of heavy weapons were delivered to Shia Houthi rebels in Yemen on Sunday via the Red Sea, informed sources told a pan-Arab newspaper.
The anonymous sources told Asharq Al-Awsat that cargos arrived in Yemen through the ports of Midi and Houdayda. The weapons were sent by Iran, the sources claimed.
They also said Yemeni naval forces were under the control of Houthi insurgents, and there is a "conspiracy" inside the Yemeni army.
"The army's response to the Houthis attacks is very weak and none of Saleh's assets were attacked or touched by them. The army's leaders are known for their loyalty to Ali Abdullah Saleh," the sources continued.
The weapons include heavy artillery and heavy machine guns that are used to destroy houses and institutions, in addition to landmines and bombs that target military camps.
Anti-Houthi protests have spread across Yemen, with people calling for the rebels to leave their villages and cities.
In early November, local Al-Qaeda leader Nasser Al-Wahishi claimed the Houthi rebels, who dominate large swaths of the country, have connections with Iran, and both of them want to eliminate Sunnis.
Al-Qaeda killed two hostages on Saturday: 33-year-old American Luke Somers and 57-year-old South African Pierre Korkie. The United States had launched a rescue operation and sent 40 Special Forces officers to the Al-Qaeda's hideout where a heavy fight erupted.
The US official thought the hostages were killed during the surprise attack, five militants were killed and a number of US soldiers were wounded.
US President Barack Obama issued a statement describing the murder of the hostages as "barbaric."
