Pakistan is not prepared to take part in a conflict that would divide the Muslim world on sectarian lines, said Pakistani Defense Minister Khawaja Asif, The Nation reported.
"We don’t want to be part of any proliferation, we will try to contain it," he said.
"No such decision will be taken which may result in (adverse) effects in 5, 10 or 20 years," Khawaja Asif added.
The remarks came a day after Saudi Arabia called on Pakistan to join the coalition.
Saudi Arabia launched airstrikes against Yemen early Thursday, one day after the US-backed Yemeni president fled the country. Riyadh also continued its offensive against the Yemenis on Friday and left dozens of more civilians dead and injured.
Riyadh claimed that it has bombed the positions of the Ansarullah fighters and launched attacks against the Sana’a airport and the Dulaimi airbase.
But despite Riyadh’s claims, Saudi warplanes have flattened a number of homes near Sana’a international airport.
At least 25 Yemeni civilians, including children, were killed and tens of other wounded in the Saudi air strike.
Also, 15 more people were killed and injured in a second round of massive attacks by the Saudi Arabian fighter jets in the Northwestern Yemeni city of Sa’ada on Friday.
Yemen’s al-Massira TV reported that the Saudi air force targeted the Yemeni’s civilians who were shopping in a market.
Five Persian Gulf States — Saudi Arabia, the United Arab Emirates (UAE), Bahrain, Qatar and Kuwait — backed by the US have declared war on Yemen in a joint statement issued earlier Thursday.
The Saudi aggression has received growing international condemnation as it is pushing the region and the world into an unprecedented fast-growing war as its ISIL mercenaries are on the brink of complete annihilation in Iraq and Syria.
