Finland has announced plans to grant two million euros in humanitarian aid to the refugee agency UNHCR's operation in Lebanon, according to the foreign affairs ministry.

The government said the aid will go towards supporting refugees and internally displaced individuals amid escalating hostilities in the Middle East.

It said the situation has "led to a rapidly worsening humanitarian crisis in Lebanon".

The ministry estimates that there are more than one million displaced people in Lebanon, a country with a population of around 5.8 million.

It said that it expects that number to rise, as military strikes continue in the region.

"The humanitarian situation in Lebanon is very dire. The UNHCR focuses support to vulnerable groups, such as families with children and persons with disabilities, by providing accommodation and basic commodities, among other assistance," Foreign Trade and Development Minister Ville Tavio (Finns) said in a press release.

The ministry noted that Finland made another tranche of humanitarian assistance to Middle Eastern countries earlier this year.

"In total, Finland granted approximately 19 million euros in flexible, targeted humanitarian funding to organisations that respond to the humanitarian situation in Lebanon, among other countries," the ministry's release read.
