US President Barack Obama has rejected the proposed Keystone XL oil pipeline from Canada, saying he could not vouch for its safety by a deadline, despite intense election-year pressure.
The rival Republican Party had forced Obama to make a decision on whether to approve the 2,700 km route through the Great Plains to Texas, forcing him to choose between environmentalists and industry.
The Obama administration said on Wednesday that the company TransCanada could resubmit the Keystone XL project, but that officials were not able to assess its plan by a February 21 deadline put into law by Republicans in Congress.
TransCanada has said that it would re-apply.
