At least 82 Houthis were killed in air strikes near Yemen’s strategic city of Marib, during a second week of intense reported bombing the Arab coalition said on Wednesday.

This is the 10^th consecutive day that the coalition has announced strikes around Marib, reporting a total of around 1,300 Houthi fatalities.

Most of the previously announced strikes were in Abdiya about 100 kilometers (60 miles) from Marib — the internationally recognized government’s last bastion in oil-rich northern Yemen.

“Operations targeted 11 military vehicles and killed more than 82 terrorist elements” in the past 24 hours in the districts of al-Jawba and al-Kassara, the coalition fighting in Yemen said in a statement carried by the official Saudi Press Agency.

Al-Jawba lies about 50 kilometers south of the city and al-Kassara is about 30 kilometers northwest.

According to a government military official on Wednesday, the Iran-backed Houthis have made “small advances” in al-Jawba amid clashes with Yemeni troops.

The Houthis began a major push to seize Marib in February and have renewed their offensive since September after a lull.

The Yemeni civil war began in 2014 when the Houthis seized the capital Sanaa, 120 kilometers (75 miles) west of Marib, prompting the Arab coalition forces to intervene to prop up the government the following year.

Tens of thousands of people have died and millions have been displaced in what the United Nations calls the world’s worst humanitarian crisis. The seven 7 years of dispute have killed or injured at least 10,000 children, the United Nations children’s fund, UNICEF, said on Tuesday after a mission to the country.
