Airstrikes continue on military sites in Yemen

The five-day humanitarian pause began last week to enable the UN to deliver humanitarian aid to Yemenis.

However, during the truce, clashes between Houthi fighters and forces loyal to exiled President Abd Rabbu Mansour Hadi continued as both sides trade accusations of breaching the cease-fire.

On the last day of the shaky truce on Sunday, intense fighting in Yemen's southern province of Taiz killed at least 20 people.

Saudi Arabia, along with eight other Arab states, have been bombing the Houthi group and forces loyal to former president Saleh since March 26, aiming to reinstate the government of president Hadi, who was forced to flee the country.

A dialogue conference with the participation of several Yemeni political parties, tribes, representatives of country's parliament as well as envoys of regional and international organizations started on Sunday in Riyadh.

However, the Shiite Houthi group and leaders of the General People's Congress party, led by Saleh, boycotted the talks.

The seven-week air strikes, as well as the ground battles between Houthis and Hadi's supporters, have so far killed more than 1,400 people, while over 4,000 others were wounded across the crisis-ridden country, according to data released by the Yemeni government.
