German and Omani foreign ministers called for a cease-fire in Yemen on Tuesday as a UN special envoy and a senior Iranian diplomat also arrived in the German capital of Berlin for talks to end the Saudi-US aggression.

"The recent bombings of ports and road blockades in Yemen have made it much more difficult for international humanitarian organizations to deliver aid to civilians," German Foreign Minister Frank-Walter Steinmeier said at a press conference with his Omani counterpart Yusuf bin Alawi bin Abdullah as he slammed the recent Saudi-led airstrikes on the cities and urged for a cease-fire to ease civilian suffering.

Steinmeier backed Oman’s diplomatic efforts to help the UN broker a political solution to the conflict, and said special envoy to Yemen, Ismail Ould Cheikh Ahmed, would also have talks in Berlin later Tuesday.

"We have agreed today to remain active in appealing partners in the region towards reaching for at least a cease-fire in the very near future," Steinmeier said.

Bin Alawi expressed grave concerns for the ongoing fighting in neighboring Yemen and vowed to continue diplomatic efforts.

"We hope that our Yemeni brothers, despite all their disagreements, will grasp the opportunity to talk to each other and stop the bloodshed," he said.

As Germany and Oman stepped up efforts for a cease-fire in Yemen, Iranian Deputy Foreign Minister Hussein Amir-Abdollahian arrived in Berlin for talks on Yemen and Syria.

Diplomatic sources confirmed that Abdollahian would hold high-level talks with German officials Tuesday and Wednesday, and would also meet Markus Ederer, state secretary of the German Foreign Ministry.

Ederer made various visits to Iran and Saudi Arabia in the last couple of months to facilitate a cease-fire and a political solution to the conflict in Yemen.
