Saudi-led air raids hit the Yemen capital Sanaa overnight, targeting forces loyal to former president Ali Abdullah Saleh in the east and south of the city, residents said on Tuesday.
The strikes are the first to hit the capital after a five-day ceasefire ended late on Sunday, although military operations resumed earlier on Monday in northern Saada Province and in the southern city of Aden, Reuters reported.
Saudi Arabia and its Arab allies have been conducting an offensive against Houthis forces and units loyal to Saleh for more than seven weeks, part of a campaign to restore fugitive president Abd-Rabbuh Mansour Hadi to power.
The truce ended despite appeals by the United Nations and aid groups for extra time to allow badly needed humanitarian supplies into the country of 25 million people, one of the poorest in the Middle East.
The UNHCR reported that the last two of six planes carrying UNHCR aid reached Yemen on Monday, boosting relief stocks in the war-ravaged country.
In addition, the UN said Tuesday that some 1,850 people had been killed and more than 500,000 have been displaced as a result of the conflict raging in Yemen since late March.
More than 1,850 people had been killed and more than 7,400 had been injured, the UN humanitarian agency said citing numbers from Yemen health facilities.
