The Libyan government on Sunday dubbed Egyptian president’s military intervention threat as a “declaration of war.” 

“The statements of the Egyptian President [Abdel-Fattah Al-Sisi], which are harassing Libya's sovereignty and meddling in its internal affairs, and supporting putschists, militias and mercenaries in Libya are unacceptable,” the government’s press office said in a statement.

“These are seen as hostile steps and clear intervention to internal affairs, and a declaration of war,” it added.

In a television speech in the Egyptian city of Matrouh near the Libyan border on Saturday, al-Sisi suggested that Cairo could launch "external military missions" into Libya "if required," saying that "any direct intervention in Libya has already become legitimate internationally."

Al-Sisi told his army to "be prepared to carry out any mission here within our borders, or if necessary outside our borders."

The Libyan government said it has always called for a political solution, however, eastern Libya-based warlord Khalifa Haftar and his supporters started to attack the capital Tripoli.

Many countries closed their eyes to violations and crimes by Haftar, it said.

Noting that those countries started to talk about “political solution and dialogue” as Haftar forces suffered defeat, the Libyan government said that now they resort to intervention threats.

Highlighting that “all of Libya is the red line,” it said those lines are not drawn by such statements but by the blood of martyrs, in reference to al-Sisi’s remarks, who said: “Sirte and Jufra are the red line.”

The UN recognizes the Libyan government headed by Fayez al-Sarraj as the country's legitimate authority as Tripoli battles the militias of Haftar.

The government launched Operation Peace Storm against Haftar in March to counter attacks on the capital, Tripoli, and recently liberated strategic locations, including Tarhuna, Haftar's final stronghold in western Libya.

It has severely condemned military backing by Egypt, the UAE, France and Russia to Haftar's attacks on Tripoli, which began on April 4, 2019.

Libyan premier talks to commander of Sirte-Jufra region

Libya’s prime minister and the commander in charge of the Sirte-Jufra Joint Operations Unit met Sunday to discuss measures for the safety of civilians following remarks by Egypt’s president.

According to a statement on the Libyan government's Facebook page, Fayez al-Sarraj, the head of Libya’s internationally-recognized government, and Ibrahim Ahmad Baytulmal met following statements by Egyptian President Abdel Fattah el-Sisi on Libya's coastal city of Sirte and al-Jufra airbase.

During the meeting, Baytulmal informed the prime minister about the course of the operations and the coordination mechanisms that have been established with other military regions.

On Saturday, al-Sisi alluded to the possibility of sending "external military missions if required" and said that "any direct intervention in Libya has already become legitimate internationally” while speaking in the city of Matrouh near the Libyan border.

He told his army to "be prepared to carry out any mission here within our borders, or if necessary outside our borders."

"Sirte and Jufra are a red line," he added.

Despite the baseless arguments of warlord Khalifa Haftar and his supporters, the UN recognizes the government headed by al-Sarraj.

The government launched Operation Peace Storm against Haftar in March to counter attacks on the capital and recently regained strategic locations including Tarhuna, Haftar's final stronghold in western Libya.

The Libyan government has condemned the military support by Egypt, the United Arab Emirates, France and Russia for attacks by Haftar's militias on Tripoli, which began on April 4, 2019.
