According to Al Jazeera sources, the Saudi-Emirati coalition air raids on Kamaran Island and Ras Issa in Al-Salif district in Hodeidah province in western Yemen, killing eight people and wounding others.
A few hours after the midnight raids, violent clashes erupted between the Houthis and government forces on the eastern and southern outskirts of Hodeidah, the first since the establishment of joint security checkpoints about a month ago.
The violence threatens to break the truce stemming from an agreement last December to neutralize Hodeida, the main lifeline for millions of people.
In a related context, said two local officials - on condition of anonymity - that the raids of coalition aircraft targeted military sites were "surprising", and also included sites near the port of Hodeidah on the island of Kamran nearby.
In the morning, violent clashes took place at the southern and eastern sides of the coastal city, in which both sides used cannons and mortars.
The war in Yemen between the Houthis and forces loyal to President Abd Rabbo Mansour Hadi's government has been going on since 2014, and intensified in March 2015 as Saudi Arabia intervened at the head of the military alliance in support of government forces.
The majority of commercial goods and aid destined for residents in Houthi-controlled areas pass through Hodeidah port, which has been controlled by the Houthi group since 2014.
These events come after a decline in overall violence in Yemen, with the Houthi group stopped bombing Saudi Arabia since last September, and the Kingdom announced an open channel with them to reach a peaceful solution to the war.
The war in Yemen has left about 10,000 dead and more than 56,000 wounded since the start of coalition operations, according to the World Health Organization, but a number of humanitarian officials believe the actual death toll is much higher.
