PRAGUE, March 24 (Reuters) - Czech and Slovak police have detained three people, including U.S. and Czech citizens, on terrorism charges following an arson attack on an arms producer's facility claimed by a group that says the company develops weapons in cooperation with an Israeli firm.

Two of the suspects from Friday's attack were detained in the Czech Republic and one in Slovakia, Czech police said on X on Tuesday.

"We continue to work intensively to apprehend the remaining suspects, also in cooperation with foreign partners," the police said.

ISLAMABAD, March 24 (Reuters) - Pakistan's role as a possible host of talks aimed at ending the Iran war builds on its courtship of U.S. President Donald Trump and its reputation as a relatively neutral player with long-standing ties to neighbouring Iran's Islamic Republic.

If talks happen, it could raise Pakistan's global prominence to heights not reached since Pakistan helped mediate the secret diplomatic opening that led to U.S. President Richard Nixon's visit to China in 1972.

DUBAI, March 24 (Reuters) - Iran named a former Revolutionary Guards commander and senior figure in the hardline political faction on Tuesday to replace the powerful head of the Supreme National Security Council, Ali Larijani, killed in U.S.-Israeli strikes last week.

Here are the latest developments in the Middle East war:

BRUSSELS, March 24 (Reuters) - The European Commission will no longer submit a legal proposal to permanently ban Russian oil imports over Moscow's war in Ukraine on April 15 as previously planned, an updated EU legislative agenda showed on Tuesday.

An EU official, however, told Reuters the proposal had not been cancelled and would still be published though no longer by the mid-April date due to "current geopolitical developments".

German President Frank-Walter Steinmeier spoke on Tuesday of a "deep rift" with traditional ally the United States and said the US-Israeli war on Iran was a "breach of international law".

In unusually strong comments, the German head of state said that just as there was no going back from Russia's 2022 full-scale invasion of Ukraine, "there will be no going back to before January 20, 2025", when US President Donald Trump entered the White House for a second time.
