Bahrain hosted a conference on Gulf maritime security on Wednesday, after multiple attacks on shipping in the strategic Strait of Hormuz sent tensions soaring between Iran and the US.
Manama said the meeting was held "to discuss the current regional situation and to strengthen cooperation".
In a statement, it slammed "the repeated attacks and unacceptable practices of Iran and the terrorist groups linked to it."
In light of the recent challenges and threats facing the region, Bahraini Foreign Minister Sheikh Khalid bin Ahmed Al Khalifa, stressed the importance of regional and international cooperation, calling upon the international community to assume its role in deterring all threats that target international security and peace.
The closed-door meeting was confirmed by the British Defense Ministry and a spokesman for the US Marines' 5th Fleet on Tuesday. The ministry declined to give details about the agenda, but said that "several international partners" would be participating.
The Guardian reported this week that the UK had called for the meeting in Bahrain with other European countries and the US.
Bahrain said earlier this month that it and the US would co-host another conference on "maritime and air navigation security", set for October.
Meanwhile, German Foreign Minister Heiko Maas said on Wednesday that his country will not participate in a US-led naval security mission in the Gulf.
Washington asked Berlin to help safeguard shipping in the Strait of Hormuz after Iran's recent seizure of a British-flagged oil tanker.
"The German government will not take part in the maritime mission presented and planned by the United States," Maas said while on an official trip to Poland.
He said Germany disagreed with Washington's approach towards Iran and is not seeking a military escalation to the crisis.
The US and Britain have been seeking to establish a mission to prevent Iran from seizing further oil tankers, after Tehran impounded the British-flagged Stena Impero and the Panama-flagged MT Riah in mid-July in the Strait of Hormuz.
Several EU member states have expressed an interest in the proposal to ensure safe travel of cargo.
