BAGHDAD — Five bombs exploded in the Iraqi capital on Saturday, killing 30 people, as tensions continued between Baghdad and Jordan, signaling the inexorable spillover of Iraq’s troubles to the region.

The dispute between the two nations centered on a meeting held in Amman, the Jordanian capital, on Wednesday evening by 11 Iraqi Sunni groups, including some that are actively fighting the Iraqi government.

The Jordanian government was not involved in the meeting, but after the groups put out a strident statement asking other nations not to side with the Iraqi government in its conflict with Sunni militants, the Iraqis were angry that Jordan had allowed the meeting to take place.

Iraq recalled its ambassador and the Jordanians apologized on Friday, but Iraqi Parliament members are accusing Jordan of knowing the groups were there and not arresting them.
