LONDON: Three Qatari coastguard vessels stopped two Bahraini coastguard boats that were returning after taking part in a maritime exercise on Wednesday.
The Bahraini vessels were then allowed to go, Bahrain's interior ministry said in a statement.
Bahrain considered it “an act inconsistent” with a security agreement between the Gulf Cooperation Council (GCC).
The state said it would notify the GCC and hoped the incident, which took place at 1 p.m., would not be repeated.
