Ukrainian President Volodymyr Zelensky arrived in Brussels Thursday seeking to rally support from Europe as his relations with US President Donald Trump have taken a fresh battering.

Zelensky said he would meet NATO chief Mark Rutte and hold a string of bilateral talks with European leaders before joining an EU summit on Friday.

The United States is considering using its biggest non-nuclear bomb against Iran if President Donald Trump should decide to renew combat in the war that has hit a deadlock, CNN reported Thursday.

The military is planning for the potential use of the GBU-43/B Massive Ordnance Air Blast (MOAB) bomb -- better known by its nickname, the "Mother Of All Bombs" -- to target Iranian energy infrastructure and nuclear sites, according to the news outlet, which quoted officials familiar with the matter.

Authorities on Wednesday raided the headquarters of one of Turkey 's few broadcasters not aligned with the government, and appointed a trustee manager to oversee it as part of an investigation into alleged corruption.

Press freedom groups and opposition parties, however, denounced the move against Halk TV — a popular news channel — calling it yet another step by the government to silence opposition voices.

Bulgaria on Wednesday said Russia was likely behind drone attacks that struck four ships in the Black Sea in the past week, sinking two, but there was no way of proving Moscow's culpability.

Rescuers are still searching for 11 crew members missing after drone strikes on Tuesday sank two ships in Bulgaria's exclusive economic zone and adjacent waters, while five other crew members were rescued.

The United States is helping Russia in its war with Ukraine, a senior Ukrainian official told AFP on Wednesday, blaming Washington for not warning Kyiv about incoming strikes and slowing Starlink.

"There have already been two cases where the Americans did not provide warnings about Russian ballistic launches, a massive ballistic attack against our energy sector... And on top of that they've throttled Starlink speeds," said the official, who asked not to be identified.

Massive Russian strikes on Ukraine on Wednesday left some 600,000 people without power and deliberately flouted a purported "energy ceasefire" announced by Donald Trump, President Volodymyr Zelensky said.

"A targeted Russian ballistic missile strike specifically against energy infrastructure –- the very infrastructure covered by the ceasefire announced by the American President," he wrote on X.

Political tensions mounted on Tuesday over the European Union's next long-term budget as pressure builds to get the spending package agreed before a series of unpredictable elections in some of the biggest member countries next year.

The EU budget, known as the multiannual financial framework, amounts to around 1.2% of the 27-nation bloc's gross national income. The MFF is financed mostly by the member countries based on the size of their economies.

Ukraine received no early warning from its partners about a Russian ballistic missile strike on Kyiv in which five missiles hit civilian infrastructure, President Volodymyr Zelensky said Tuesday in a post on X.

Zelensky characterized the barrage on the capital as "particularly vile," and emphasized that receiving intelligence from Ukraine's partners on such ballistic missile attacks "helps save lives, and this is one of the most critical issues."

King Felipe VI and Queen Letizia kicked off their first visit to Ceuta on Tuesday in a show of solidarity with residents of the Spanish city in North Africa as they grapple with a migration crisis that has strained relations with Morocco.

The royal couple will then travel to Melilla, Spain's other North African exclave, on Wednesday. It will be the first visit by a Spanish monarch to the two cities since Felipe's father, Juan Carlos I, toured them in 2007.

Drones struck two ships in the Black Sea off Bulgaria, sinking one and prompting emergency rescue operations, Prime Minister Rumen Radev said early Tuesday.

One crew member from the sunken vessel was rescued, he said, without providing details on the others aboard.
