A Saudi Arabia-led coalition of Arab nations has declared an end to a two-week ceasefire with Yemen's Houthi rebels.

"The leadership of the coalition supporting legitimacy in Yemen announces the end of the ceasefire in Yemen beginning at 2.00 p.m. (1100 GMT) on Saturday," the coalition said in a statement released by Saudi Press Agency (SPA), according to Saudi Gazette.

The grouping further said that the continuous violation of the ceasefire agreement by Houthi rebels has forced the coalition to resume the airstrikes.

"The militias have continued to shell residents and kill and detain Yemeni civilians in cities under their control. All this shows how unserious the militias and their allies are and their disregard for the lives of civilians, and how they have clearly exploited this truce to make gains," the statement said, according to Al Arabiya.

The ceasefire agreement between two sides was announced on Dec. 15 after the resumption of U.N.-mediated Yemen peace talks in Switzerland, DW reported.

Saudi-supported forces loyal to President Abd Rabbuh Mansur Hadi, forces loyal to former president Ali Abdullah Saleh and Houthi rebels have reportedly violated the ceasefire.

The U.S.-backed Saudi coalition has been fighting Iran-backed Shia Houthi rebels in Yemen since March of last year.
