Violations of the Yemeni ceasefire are said to have begun as soon as the truce was implemented at 23:59 local time yesterday evening.
According to local resistance sources in Yemen's besieged city of Taiz, Houthi rebels were shelling the Hasnat and Tha'abat neighbourhoods in the east of the city.
Houthi and Saleh militias then continued to shell positions of opposition forces who consist of local resistance units and forces loyal to current Yemeni President Abd Rabbuh Mansur Hadi.
Taiz has been besieged by the Houthi rebels and forces loyal to former President Ali Abdullah Saleh for the past 18 months.
There were further reports of ceasefire violation in Yemen's capital city Sana'a, which has been under Houthi and Saleh control since September 2014. Pro Houthi and Saleh forces bombed the Nehm area, which is where local tribes and pro Hadi forces made significant gains at the beginning of this month.
At around 01:30, Houthi and Saleh forces shot at national army and resistance positions in Al-Mekhdera area with machine guns. No one was reported to have been hurt in any of the attacks.
It appears that these were isolated attacks by the fighters themselves.
Yemen has been locked in a bitter battle between Shia Houthi fighters allied with forces loyal to ousted President Ali Abdullah Saleh and government forces led by President Abd Rabbuh Mansur Hadi, along with local tribes and resistance forces backed by the Saudi-led coalition's airstrikes.
