Six ships have turned back in the past 24 hours after Yemen's armed forces imposed a maritime ban on Saudi vessels.

Yemen says it has become a regional military power and has already imposed a naval blockade on Saudi Arabia.

Yemen’s Foreign Ministry has warned Saudi Arabia of “adverse and serious consequences” if it seeks to foment tensions, and escalates attacks and blockade against the Arab nation.

The spokesperson for the Yemeni Ansarullah resistance movement says the naval blockade against Saudi Arabia is a natural and legal response to the kingdom’s adamant refusal to take heed of the Yemen nation's demands.

Yemen has declared a naval blockade against Saudi Arabia, with the country’s military spokesman stressing that it will come into effect immediately.

Ansarullah official says aggression against Iran and the blockade on Yemen is pushing the region toward a major blast.

The strategic importance of the Bab al-Mandab Strait, combined with Yemen's growing missile and drone capabilities, has fundamentally reshaped regional security calculations, according to a Yemeni analyst.
