A group of senior Pakistani officials have arrived in Saudi Arabia to assess whether they will join the Saudi-led coalition against the Shiite Houthi rebels in Yemen.
Pakistani Defence Minister Khawaja Asif says his side has been in-contact with the Saudis over the past few days. "We took a clear stand that any violation of the territorial integrity and sovereignty of Saudi Arabia would evoke a strong reaction from Pakistan and we will support our Saudi brothers. No one should doubt it."
Saudi Arabia, supported by its Sunni Muslim allies in the region, began launching air strikes against the Shiite Houthis last week.
The Houthis now control much of Yemen.
Yemeni government authorities and their Sunni allies have accused Iran of being behind the Houthi offensive.
Iranian authorities have denied any involvement, and are calling for an end to the Saudi-led offensive in Yemen.
Hossein Amir Abdollahian is Iran's Deputy Foreign Minister for Arab and African Affairs.
"Continuing the aggression on Yemen will only lead to support and out-sourcing for terrorism in this country and in the entire region. We think that the aggression, which was launched on Yemen, is useless and it will expose the entire region to danger. We see that security in Iran and the region is integral and therefore we will make all the efforts to stop this aggression on Yemen and to go back to the National Yemeni Dialogue Conference."
Meanwhile, the United Nations is warning that Yemen is on the edge of a humanitarian crisis.
The UN has also issued a statement condemning an attack on a camp for refugees in northern Yemen which left at least 40 people dead.
Both the Houthis and the Saudis are blaming one-another for that incident.
