The Iran-backed Houthi militias in Yemen view Israel's recognition of Somaliland as direct threat, warning that any Israeli presence in the separatist region will be considered a military target.
Somaliland declared independence from Somalia in 1991. The region has operated autonomously since then and possesses its own currency, army and police force.
Diplomatic isolation has been the norm -- until Israel's move to recognize it as a sovereign nation, which has been criticized by the African Union, Egypt, the six-nation Gulf Cooperation Council and the Saudi-based Organization of Islamic Cooperation.
The European Union has insisted Somalia's sovereignty should be respected.
Houthi leader Abdelmalik al-Houthi said Israel's move was an "act of aggression on Somalia, Yemen and the security of the region."
In a statement, he added that Tel Aviv was seeking to establish "a military and intelligence foothold" in one of the world's most important waterways. He also warned that any Israeli presence in the region will be deemed a "legitimate target" for the Houthis.
Somaliland is strategically located at the entrance of the Gulf of Aden and close to the Mandeb Strait. It is one of the world's busiest waterways.
Analysts said that Israel's recognition gives it a direct outlet to the Red Sea, boosts its ability to monitor waterways and perhaps allows it to carry out military or intelligence strikes against its rivals, notably the Houthis in Yemen.
Since October 7, 2023, the Houthis had launched rocket and drone attacks against Israel and targeted ships affiliated with it in marine shipping lanes. Israel retaliated by carrying out attacks against Houthi targets in Yemen. The attacks by both sides ended with the announcement of the ceasefire in Gaza.
Political sources said the Houthis are alarmed at the prospect of Israel having a presence in Somaliland. In their view, this will lead to them being surrounded from the southwest. They also fear that Somaliland will be used as a platform for Israeli attacks against them in Yemen.
